Winix HR900 Ultimate Pet Air Purifier review: features

One of the big plus points of the Winix HR900 Winix HR900 Ultimate Pet air purifier is its in-depth cleaning process. First, an Ultimate Pet Pre-filter traps the largest particles, such as pet hair and dander; then a washable fine mesh pre-filter picks up any other large particles that have slipped past the first filter. Both pre-filters help extend the life of the finer filters. 

Next, the Activated Carbon filter traps pet odors, as well as smoke, chemicals and VOCs (volatile organic compounds), helping make your indoor air fresh. Following that is a True HEPA filter – they're becoming increasingly common in air purifiers, and for good reason. The one in the Winix HR900 Ultimate Pet can capture up to 99.97 per cent of particles down to 0.3 microns, including mold spores, pollen, virus particles and allergens.

Finally, the Winix PlasmaWave ionizer further reduces the amount of harmful particles. Bear in mind that Ionizers sometimes release ozone, which can be irritating to people with asthma or allergies – but the Winix HR900 lets you turn this off, which is particularly useful.

Winix HR900 Ultimate Pet Air Purifier review: performance

Another important point to mention is unlike premium air purifiers – such as the Rabbit Air MinusA2 or Austin Air HealthMate – the Winix HR900 Ultimate Pet pre-filter is just a paper filter. It does the job, but it's easily broken and can need to be replaced regularly. However, it's difficult to find an air purifier in this price range that includes a filter like this at all.

Aside from the five-step air purification process, one great feature of the Winix HR900 is its smart sensor. Not only does this monitor your air quality, but it also offers real-time feedback via a color-coded light system on the front of the air purifier, so you can see how clean your air is at a glance. The Winix HR900 can then use this information to automatically adjust the fan speed for efficient cleaning.

Lastly, a handy sleep mode reduces the fan speed to keep the Winix HR900 quiet. it also turns off light notifications for an undisturbed night’s sleep.

Testing revealed that the odor control and vapor absorption ability of the Winix HR900 was some of the best the site has ever tested. The team also found that it did a great job of cleaning pet hair, as well as capturing odors, dander, and microscopic dust.

The Advanced Odor Control filter was not only an unusual design but incredibly effective. (So if pet smells are a particular problem for you, this air purifier could be a great choice.) The team also praised the quiet and soft sound of the fan, which meant that any noise it did make was barely noticeable.
