Winix U300 Air Purifier: Five Stages Of Cleanliness
If you have allergies, then you know very well the importance of keeping your air clean. It can be a difficult task, whether you’re in the city or the country- pollen, pets, and other types of pollutants can quickly overwhelm, even not considering smoking. Keeping your windows shut might help, but there are still plenty of ways for your environment to be affected.
The Winix U300 Air Purifier can handle any of them, thanks to five distinct layers of filtration and protection. It’s not a small unit, and it doesn’t hide away or mount against a wall like some we’ve seen. But it offers a nice balance of power and size for the price, without being too noisy. Built for rooms up to 300 square feet, like most units in this range, you’ll probably focus most on the bedroom- or a small apartment. With a CADR rating of 197 cfm for dust and smoke, it can handle some serious tasks.
We set it up and noticed a difference within a couple of hours, especially when cooking or during seasonal peaks. The five stages are pretty common amongst competitors, but often have different names- here they are a washable pre-filter, CleanCel antimicrobial coating, a 99.97% efficient True-HEPA Filter, an odor control washable carbon filter, and their patented PlasmaWave Technology which uses ‘hydroxyls’ to neutralize airborne viruses, chemical vapors, and even gases. Four speeds offer a lot of flexibility, ranging from 70 to nearly 300 square meters of airflow, and 28-58 decibels of sound- enough to notice at high speed, but barely a whisper for night time operation.
We liked the included remote, something not every model includes. And the white color goes with everything, though the plastic body doesn’t feel as solid as some alternatives. It’s important to note that you’ll need space on all sides of the unit as well- you can’t just set it in a corner, against a wall. It is easy to clean, though not simple to move, and the all-in-one filters are simple to install and, we suspect, replace. A five year warranty is excellent, though the company does indicate you’ll need to replace the carbon filter every three months. For $280 or so, online and in stores, the Winix U300 Signature HEPA Air Cleaner is a great middle of the pack unit, ideal for smaller rooms.
