My house has a lot of indoor air pollutants. We have two cats to which I'm allergic. My wife likes to vape inside. And, since our house is old and lacks a ventilation system, there is an array of other irritants that don't have an easy exit route.

This is where a good air purifier comes in handy — like the RabbitAir BioGS 2.0 Ultra Quiet HEPA Air Purifier (currently $399.95 on Amazon).

Founded in 2004 in Los Angeles, RabbitAir focuses exclusively on air purifiers and accessories. It currently offers two product lines — the MinusA2 and BioGS 2.0. I had the opportunity to test the more powerful model of the BioGS 2.0 — the SPA-625A— and here are my experiences with it.

Specs

The sleek white design won't distract from your home's decor. In fact, I thought it fit into my home quite nicely.
Rabbit Air

  • Weight: 16.8 lbs
  • Dimension: 22.2 inches high x 16.6 inches wide x 9.8 inches deep
  • Power Consumption: 5 to 39 watts
  • Noise Level: 22.8 to 50.4 dBA
  • Effective Coverage Area: 625 sq. ft. for normal residential use or 313 sq. ft. for a household with more allergens
  • Filter Life Span: Up to 18 months

The 625A model is designed to be easy to move from room to room. It only weighs 16.8 pounds, has a handle, and measures 22 inches high by 16.5 inches wide by 10 inches deep.

According to the manufacturer, the 625A purifies 313 square feet every 15 minutes. This is based on a room with an eight-foot ceiling.

There are also four stages of purification and deodorization:

  • Pre-filter: Traps and reduces large particles, dust, and allergens
  • BioGS HEPA filter: Captures 99.97% of 0.3-micron airborne particles
  • Charcoal-based activated carbon filter: Helps reduce common household smells and irritants
  • Negative ion generator: Uses negative ions to remove particles from the air and generate cleaner air. This feature can be turned off if you're concerned about the minuscule amount of ozone produced, which is less than the 0.05 ppm limit set by the super strict California Air Resources Board.

The air purifier is Energy Star-certified and only consumes 39 watts of power when on high.

Set-up process

The whole set-up process took me about five minutes.

First, you remove the front panel and take out the filters. The activated carbon and BioGS HEPA filters come wrapped in plastic so you'll need to remove the covering before you use the unit. Next, you reinstall the filters, which I actually liked because it helped me familiarize myself with the elements I would need to maintain down the road.

Before plugging in and operating your air purifier, RabbitAir recommends placing it no closer than two feet from the wall. This allows space for the air purifier to take in polluted air and release clean air.

Once I found a good spot in my bedroom, I started the SPA-625A. At this point, you can choose the fan speed, mode, or timing you want. I went with the low auto mode, which was the default setting.

What makes the air purifier stand out

I like that the 625A is Energy Star-certified so I don't go broke trying to clean my indoor environment. There are low, medium, and high auto modes that adjust the sensitivity of the air quality sensor. The higher the sensitivity, the faster the fan will clean the air when irritants are present. When there are few pollutants, the fan will operate at low speed. You can also set the air purifier to automatically turn off after four, eight, or 12 hours.

In addition to the Auto modes and timer, you can manually adjust the fan speed, of which there are five. And the 625A comes with a remote control, which I appreciated because there was no need to get out of bed to turn up the fan at the end of the night.

Like I mentioned earlier, my wife likes to vape indoors — including in our bedroom. I appreciate that she no longer smokes cigarettes, but the "cloud-chasing" can be a bit much at times. When she's puffing her clouds, you can hear the purifier ramp up to tackle them — she likes to joke that it's judging her. When she forgets to turn on the purifier while vaping, our ultra-sensitive smoke alarm inevitably goes off, so it's clear that the purifier is doing its job. Especially since when I clean the pre-filter, there's significant debris stuck to it.

Thankfully, cleaning said filters is easy. Every month or so, you're supposed to remove and clean the pre-filter. I used a handheld vacuum, but you can also clean it with water in the sink. If you use this method though, you should allow the filter to dry for about 24 hours. The activated carbon and HEPA filters should be cleaned every three months with a handheld vacuum. When the front panel is removed, there's an indicator light that lets you know when it's time to clean and replace the filters.

I liked that the RabbitAir purifier is incredibly quiet. To test how loud it is, I held a sound meter four feet from the unit and measured the ambient sound to get a good baseline. It was 38 decibels. Then, I tested the sound levels with the fan speed on low, and again, my sound meter registered 38 decibels, which makes the purifier virtually silent.

With the fan on high, it was 50 decibels — which is what you'd expect in a quiet office. I generally like to sleep with a box fan running to drown out other noise, but with the 625A, I don't need to have my fan going because it's provided the faux white noise I need.

Cons to consider

The unit has a five-year warranty and Amazon buyers have said that their purifiers are still working great after a decade of use.
Rabbit Air

The 625A arrived without the HEPA filter, which left the purifier unusable. I contacted the company's customer service, they were apologetic and immediately sent me the filter. I wasn't sure if the missing HEPA filter was a common problem so I combed through the negative Amazon reviews but didn't find any complaints, so I'm calling my experience an isolated incident.

At about $400, the RabbitAir BioGS 2.0 is not cheap. And the sticker shock continues when you realize that replacing the filters will cost you another $89.95. Is the overall cost worth it?

When considering the price, it's important to look at another long-term cost — electricity. On the low fan speed, the purifier uses a meager five watts of power; energy consumption on the highest is 39 watts.

It's also worth noting that the filters only need to be replaced every 18 months at most and only if you use your purifier 24/7. Therefore, you can squeeze three years out of the filters if you only use it 12 hours a day. Most other units on the market need new filters every 3 to 12 months.

The purifier is backed by a five-year warranty with many Amazon buyers of the original BioGS reporting that their unit has been going strong after nearly a decade of nonstop use.

The bottom line

Overall, I was happy with the performance of the RabbitAir BioGS 2.0 Air Purifier. On the low setting, you can't hear the unit running at all. On high, it makes quick work of my wife's vaping, provides nice white noise when sleeping, and even minimizes the odor of the kitty litter box.

Cleaning the purifier was effortless with the use of a hand vacuum. Though it's only ideal for spaces up to 625 square feet, the lightweight design and easy-grip handle makes it easy to move around.

Should you buy it?

Yes. I would recommend this air purifier to anyone hoping to remove dust, pollen, and other irritants from one or two rooms.

What alternatives are there?

The RabbitAir BioGS 2.0 SPA-550A is the same size, shape, and design as the SPA-625A. The main difference is that the 550A circulates 550 square feet of air twice in an hour versus the 625 square feet of the 625A. The 550A also uses less power on its top setting (29 watts) and costs $30 less.

If you need a more powerful 625A and don't mind spending $20 more on top of the price, you can get it in the Tone Leaf or Tone Royal colors.

I've also tested several Coway air purifiers. , which I also recommend if this isn't your pick.

My favorite is the Airmega 400, which has an attractive design, purifies 1560 square feet twice in an hour, and is comparably priced to the RabbitAir BioGS 2.0. It doesn't have ionization abilities though. If you wanted a smart purifier, the 400S model pairs with Alexa. The Mighty is Coway's most popular purifier with ionization abilities and can clean a 1000-square-foot room in 30 minutes. It's also quite portable at just 12.3 pounds.

Which model should you get?

If you have one or two rooms and want a brand with a proven track record and lower long-term costs, I recommend the RabbitAir BioGS 2.0 SPA-625A. If the upfront cost is too steep for you and you're not too concerned about long-term expenses, then Coway's Mighty is an affordable solution at $223 on Amazon. Or if you want to clean the air in a larger space, consider the Airmega 400.

All of the options mentioned above are excellent, and based on my testing and experience, you can count on excellent performance no matter which one you choose.

Pros: Portable, quiet, cleans the air in a 313-square-foot room in 15 minutes, energy efficient

Cons: Expensive

Molekule review: Clean air, clear breathing, and castles in the sky - iMore

Posted: 03 May 2019 12:00 AM PDT

Molekule air purifier

Sacramento, California is known as the "City of Trees" and is one of the top cities in the world with the most trees per-capita. I suffer from seasonal allergies and when March comes around, I'm miserable for about three months every year (I'm literally sneezing while writing this sentence).

When I first heard about the Molekule air purifier, my interest was immediately piqued. Instead of using a traditional high-efficiency particulate air (HEPA) filter, it destroys pollutants at a molecular level, which the company says cleans the air better and keeps those pollutants from making it back into the air. Can this new technology truly help a seasonal allergy sufferer? Have I found the miracle cure for my spring sickness? I had to find out.

Molekule

Price: $799

Bottom line: This mini appliance does something no other air purifier does; it destroys pollutants instead of just collecting them.

The Good

  • Whisper quiet fan
  • Adjust controls from your phone
  • Beautiful design
  • Subscription filter refills
  • Filters are easy to replace
  • Option of payment plan

The Bad

  • Large and heavy
  • Very expensive

Bells & Whistles

Molekule: The features

Molekule air purifier carrying handle

The Molekule air purifier is a large cylinder about two feet tall. It's got a fan at the bottom that pulls air up and a small pre-filter where larger particulates like dust are trapped. The air is then pushed up through Molekule's patented photoelectrochemical oxidation (PECO) filter, which is coated with nanoparticles that, when reacting to UV light, destroys pollutants at a molecular level. Things like pollen, pet dander, mold, bacteria, viruses, and VOCs (volatile organic compounds). Those last three are things that standard HEPA filters can't do at an efficient level (or at all in some cases).

It zaps those tiny particulates like a bug zapper zaps bugs (only not loud ... and not gross).

While running, Molekule is lit up with a blue light, which is the pollutant-killing rock star of this outfit. The clean air is then pushed out of vents on the top of the cylinder.

Molekule has an onboard touch screen controller, which allows you to change the fan force and volume between silent, auto, and boost. In silent mode, the fan runs at its quietest speed, but still cleans the air. In auto mode, the fan runs at medium speed at all times and automatically adjusts for the size of the room. Boost mode allows you to push the fan to its highest speed to work fast and hard to clear the room. It's usually used after something like a room cleaning.

The onboard touch screen also shows you the filters' current health, lets you turn on Dark Mode (which turns the lights off if you need total darkness), and makes it possible to turn Molekule on or off.

At about 18 pounds and almost two feet tall, Molekule is practically an appliance. Luckily, it has its own carrying handle. If you want to move it from one room to another, you can pick it up and carry it with relative ease (if you're capable of lifting something that's 18 pounds).

When your filters are ready to be changed (every three months for the pre-filter and every six months for the PECO filter), you'll be sent new ones via a subscription. It's important for the health and effectiveness of Molekule to sign up for the subscription filters. Currently, there is no other way to buy replacements and the filters are the most important part of the air purifier. A subscription costs $65 every six months and includes one PECO filter and two pre-filters.

To replace the filters, you'll first turn off your Molekule, then press down on the cylinder and twist counter-clockwise. This lifts the top of the cylinder up so you can pull out the PECO filter from the top and open the drawer to pull out the pre-filter from the bottom. The pre-filter will be dirty, covered with dust, pollen, and other bits of stuff that has been drawn up from the fan. The PECO filter will be nearly clean. You won't even think it needs to be changed. That means it's working. Because it's destroying pollutants at a molecular level, you're not supposed to actually see what's left behind. Though it looks clean, the PECO filter still needs to be changed every six months if you want it to continue performing properly.

Breathing clean

Molekule: What I like

Molekule air purifier dust-busting light

When I first plugged the Molekule in and started it up, I immediately worried that it would be too loud and too bright to sleep with it running. I was wrong.

At the auto level, Molekule runs quieter than a fan running on low. It's actually a very pleasant sounding white noise, but not at all room-filling. If you're particularly sensitive to noise and don't like the sound of the fan, you can actually set it to Silent Mode and it will run at its lowest speed. It will still filter the air, just not with as much gusto.

I was completely surprised to discover that I could sleep with the blue glowing light just fine.

As far as the blue light is concerned, I really didn't think I could sleep with it on. I can't sleep when my alarm clock numbers are too bright. This is a two-foot-tall cylinder that's emitting blue light for about a foot all the way around at the top. I was completely surprised to discover that I could sleep with the blue glowing light just fine.

If the light does bother you, and I wouldn't blame you if it did, you can set Molekule to Dark mode, which turns the light off. You don't want to leave it off all the time because it's the light that actually kills the micro-pollutants. Through the companion app, you can actually schedule a time for it to turn off and on. That way, you don't have to worry about remembering to turn it back on and it won't keep you awake through the night.

I change my house filters every six months because I know how important it is for filters to be clean. One of the most useful things about Molekule is its subscription service. Without even thinking or worrying about it, you'll receive a new set of filters every six months. You don't have to order anything, set a reminder, or even think about it for a second. The filters will just show up when you need them.

With a contraption such as this, you might worry about how to change the filter, but frankly, it's a pleasant experience. The Molekule design makes replacing filters actually a little fun, or at least something that makes you feel smart.

Speaking of design, Molekule looks like something Apple would make. It's like the Mac's hip, trendy younger sibling. Just as handsome, but actually a little bit cooler. When people see it in my house, they immediately ask, "What's that?" with the excited tone of a child seeing cotton candy for the first time.

Does it work? Having started out as a complete skeptical, I've been won over. It's not perfect. I still wake up with a stuffy nose and runny eyes sometimes, but not nearly as often as I do without it. Considering how bad my hay fever normally gets, I'd say Molekule has helped me through my most difficult time of the year. My significant other caught a cold during my testing of Molekule. I'm not going to assume that it saved me from catching the same cold, but I will say that I didn't get sick. Molekule does destroy viruses, including those same little rhinoviruses that cause the common cold.

Molekule: What I don't like

Molekule is nearly appliance-size big

Molekule is very big. It's more like an appliance. Obviously, in order to purify a 600 square-foot room, Molekule needs to be big. But there is no mini Molekule. Whether your room is 600 square feet or 150 square feet, you get a two-foot-tall cylinder. Once the company solidifies its place in the air purifying industry, maybe it'll design a smaller unit, but for now, you may have to reconfigure your bedroom in order to fit your Molekule.

Though Molekule reduced my allergy symptoms, it didn't eliminate them altogether.

Price is the biggest hurdle to face when deciding to purchase something that clearly works well. Is it worth $800 plus $130 per year for the rest of your life? That's a hard one to answer.

Though Molekule definitely reduced my allergy symptoms, it didn't eliminate them altogether. If I was feeling particularly itchy eyes or a headache from my stuffed up nose, I couldn't just sit in my room for a half hour and suddenly stop feeling the symptoms. For $800, I kinda hoped it would.

Bottomline

Molekule air purifier

Molekule's two filters after about 2 months of use

4 out of 5

Does it improve my quality of life? Yes. Is it a miracle cure for all allergies, no. For some people, Molekule is too much purifier for the price. If you've never really felt compelled to use an air purifier, you might consider going with something less expensive to begin with. HEPA filters do work, just not as good as Molekule.

Molekule is for those people that have adverse reactions to airborne pollutants like pet dander, people who suffer from asthma and are particularly sensitive to VOCs, people that easily catch colds. If you've tried 10 different air purifiers, hoping to finally breathe well again and are always a little disappointed with the results, Molekule will probably be the 11th and final air purifier you get. For you, it's worth the price.

Though you're paying a premium for Molekule, the company's founder and his family understand that price shouldn't be a barrier to better health. They do offer a payment plan for as low as $45 per month (depending on your credit). In the end, it's still a lot, but can be possible if you can't fork over $800 at one time.

Molekule

Price: $799

Bottom line: If you're tired of trying new air purifiers that promise the world, you may never by another one again once you've tried Molekule.

8 Best Air Purifiers For Your Home - Forbes

Posted: 14 May 2019 12:00 AM PDT

Deciding what to use to clean your home might not seem like a difficult task on the surface. Nevertheless, ensuring the devices and products you choose are both safe and effective has become a hot topic in recent years, especially now that we know more about how certain compounds and chemicals affect our health.

This is also true when it comes to choosing an air purifier. It can be challenging to find one that effectively cleans the air, fits your lifestyle, falls within your price range and doesn't look like an outdated radiator. When in doubt, it's best to turn to tried-and-true brands and products with excellent user reviews. Finds evaluated these eight air purifiers by their efficiency (how many germs they claim to suck up), their appearance (is it aesthetically-pleasing?) and price. From desktop fans to state-of-the-art machines, here are eight of the best and most versatile air purifiers on the market.

Alen BreatheSmart Classic Large Room Air Purifier

Alen BreatheSmart Classic Large Room Air Purifier

Amazon

Do you have a big home? Not a problem with the Alen BreatheSmart Classic Large Room Air Purifier. This air purifier cleans up to 1100 sq. ft. every 30 minutes without filling your house with noise. In fact, the technology is twice as quiet as that of its key competitors, even on Turbo speed. Like all high-quality air purifiers, the Alen BeatheSmart has a HEP-Pure filter that claims to capture 99 percent of airborne particles down to 0.3 microns. This combines with the device's Laser Smart Sensor, which also detects airborne particles down to 0.3 microns, to effectively clean your air of dust, pollen, allergens, and dander.

No expense is spared in the design of the air purifier, either. The Air Quality Indicator Light always reflects the real-time purity of the room's air in an easy-to-read display. Furthermore, it comes in 14 different colors and panels so you can always find one to match you home's interior. This is a high-end device, coming in at $688.

Levoit Compact Air Purifier

Levoit

Amazon

Compact enough to fit on your desk but powerful enough to remove 99.9 percent of dust, pollen, smoke, odor, mold spores and pet dander, the Levoit Compact Air Purifier is an excellent entry-level option. Rather than using a UV or ions to clean the air, the device features a three-stage filtration system. This comprises a pre-filter, a HEPA filter and an activated carbon filter. Three fan settings let you control the speed and volume of the purifier.

This air purifier was definitely designed for use in the bedroom. It features a soft optional night light with two brightness settings as well as a very quiet fan. It's not out of place on your nightstand, either, with its white or black case and sleek design. While not as feature-filled as other air purifiers on this list and better suited to small rooms than large homes, you can find it on Amazon for the low price of $83.

  Rabbit Air MinusA2 Air Purifier

Rabbit Air MinusA2

Amazon

At the opposite end of the spectrum, you'll find the Rabbit Air MinusA2, priced at $550. This one comes with all the bells and whistles: a five-speed fan, a transition light sensor and the ability to cycle the air in a 815 sq. ft. room twice every hour. It also features six layers of filters, including an upgraded BioGS HEPA filter and a customizable filter with pet allergy, germ, toxin or odor defense.

This device looks more like a high-tech thermostat than a traditional air purifier; it's designed to either stand alone or mount on the wall. While its modern design and thin case are discreet enough, the MinusA2 takes up a lot of real estate on your wall. You can personalize the screen with photos and pictures, though the MinusA2 would still look out of place anywhere but an ultra-modern space. It's a good choice for consumers who are invested in upgrading their home with today's most cutting-edge technology.

Philips Smart Air Purifier

Philips Smart Air Purifier

Amazon

It's sometimes difficult to tell how effective an air purifier is, though Philips makes it simple with a light display feature that shows you the air quality in the room, ranging from blue (good) to red (poor). Philips Smart Air Purifier also offers three distinct modes: General Mode, which sets automatically; Allergen Mode, which adjusts its speed when it detects changes in allergen levels; and NightSense mode, which automatically turns down the fan speed and dims its lights when the room is dark.

This is an exceptionally popular air purifier, partly due to the fact that it comes in many sizes and prices, ranging from $250 for a bedroom fan to $549 for an extra-large room fan. The ability to control the purifier remotely is also attractive to anyone investing in smart home technology.

GermGuardian 4-in-1 Full Room Air Purifier

GermGuardian 4-in-1

Amazon

Quiet and Alexa-enabled, the GermGuardian 4-in-1 Full Room Air Purifier is a relatively more affordable fan that can compete with many of the features of brands like Philips and Dyson. Like the Philips, the GermGuardian will monitor your air and show you whether the quality is poor, moderate or good via a Light Ring on the front of the unit. You can also pull up the accompanying GT app to see this information on more detail, as well as set alerts so that it notifies you when the air quality changes.

The GermGuardian looks like any ordinary stand-up fan, so it probably isn't winning any design competitions anytime soon. However, at a price point of $149 and with glowing Amazon reviews, it's certainly worth your consideration.

 Shop Now: $149


PARTU Air Purifier

Partu Air Purifier

Amazon

The PARTU Air Purifier claims to be the quietest on the market, which is big news for anyone who's struggled to sleep to do a whirring, noisy fan. At its lowest speed, the PARTU creates 25db of noise; this is just above the sound of leaves rustling, which clocks in at 20db, for comparison. A fairly basic device, its most notable features are a multicolor light setting and a memory function that remembers your last chosen setting when you turn it on.

This isn't the most stylish air purifier of the bunch; guests will definitely know its purpose when they walk in the room. But it's still relatively compact at 17 inches in height, making it easy to stow away, and is the least expensive in-home device of the pack at $80.

  Dyson Pure Cool Link Desk Air Purifier

Dyson Pure Cool Link Desk Air Purifier

Amazon

Dyson has long been known as an innovator in the home cleaning space, though its product line recently evolved beyond vacuums to include technology like purifying fans. The Dyson Pure Cool Fans come in two sizes: a tower and a smaller desktop size. The Desk Air Purifier earns its spot on this list because it's significantly less expensive than its larger counterpart — though at $399, it's still an investment. We've recently seen it on sale for as low as $364 on Amazon, however, so keep your eyes peeled.

Inside the fan itself is a Dyson HEPA filter, complete with a layer of activated carbon granules that capture odors and harmful toxins like paint fumes. But the real appeal of this product is its portable size. At just 25 inches tall, it fits neatly into small spaces like laundry rooms and home offices where a stand-up fan might be cumbersome.

Molekule Air Purifier

Molekule Air Purifier

Molekule

 This is the most expensive air purifier on the list, sitting at $799, but for serious allergy-sufferers, this is as good as it gets. Unlike most other purifiers, which have HEPA filters that collect particulates from the air, the Molekule actually removes indoor air pollutants and destroys them. It does this using a dual-filtration system: first, the Pre-Filter catches larger pollutants like dander and pollen; then, the Nano-Filter cleans the air, claiming to eliminate airborne pollutants that are 1,000 times smaller than those the average air purifier can destroy.

 The materials used to create the Molekule aren't just functional; the design is sleek and elegant, featuring a leather handhold strap and a machined aluminum case. This air purifier is only available on the company's site, not Amazon, so it's tough to get a sense of how customers feel about the Molekule. The reviews on the site are mostly positive, however, with a few complaints about connectivity and customer support.
