Nordic Pure's MERV 12 filters are not the only products that meet all our criteria, but they are perfectly good examples, and they're usually competitively priced and easy to find online. We like that they're genuinely MERV-certified, because unlike the proprietary ratings used by some bigger-name brands, the MERV criteria are publicly available. Being rated MERV 12, the Nordic Pures will remove at least 35 percent of particles in the 0.3-to-1.0-micron range, which includes bacteria and smoke; at least 80 percent of 1.0-to-3.0-micron particles, which include fine dust and soot; and at least 90 percent of larger pollen, dust, pet hair, and lint particles. Again, MERV stands for Minimum Efficiency Reporting Value, so this is the worst performance measured during third-party testing to the ASHRAE 52.2 standard. And again: the MERV test measures a single pass of polluted air through the filter. In your home, the air will continuously recirculate when your HVAC system is, leadin...

Our pick The quietest, strongest, and most efficient window fan we've tested stands apart from all competitors, though it is a bit more expensive. Buying Options In our tests, the Vornado Transom produced a powerful yet pleasant breeze that filled the entire room with enough strength to shake strings and sheets of paper more than 24 feet away—and it did that while using half as much energy as the competition. It's roughly half as tall as the competition, too, with a sleek modern design and sturdy foam side pads that help you get a much tighter seal on the window frame. In addition, the Transom comes with plenty of other thoughtful features, including an auto-dimming LCD control panel, a remote control, and a weather-resistant design, as well as a reliable five-year warranty. It's not the easiest fan to clean, but otherwise it's the best window fan we've tested in more than seven years of firsthand comparisons. Upgrade pick This variant of our top pick adds voice com...

Did you know the air can be significantly more polluted inside our your home than the outside world ? The good news is that it's easy to make your home allergy-friendly thanks to all the plug-and-play air purifiers on the market.  As our expert consultant and air-quality specialist, Dr. Paula Olsiewski, notes, air purifiers with HEPA filters remove particles that can trigger or exacerbate symptoms of asthma or allergies. We all can benefit from using air purifiers at home because they reduce the particulate matter in the air, diminish routine exposure to airborne disease, and lower risks of respiratory conditions, such as asthma. In the Health lab, we tested dozens of air purifiers for different allergy concerns. We evaluated them based on setup, design, noise level, feature, value, and overall experienc...
