Winix HR900 Ultimate Pet Air Purifier: What is it?

The Winix HR900 Ultimate Pet is one of the best air purifiers on the market, and its additional pet features make it a formidable cleaning tool for those who share their homes with furry friends. It may now be superseded by the Winix HR950 and Winix HR1000 air purifiers, but in terms of value, the cheaper Winix HR900 has both models beat. 

Its innovative design allows the Winix HR900 to pull in air for purification from the front and sides through a perforated grill – giving it a 360-degree intake around the front plate – before pushing the air back out through the top. Inside, a five-step air purification system provides in-depth cleaning, capturing larger pet-related particles, such as hair and dander; odors, like those from pet litter and food; and other tiny particles.

Winix HR900: Price

The Winix HR900 Ultimate Pet air purifier cost $349.99 at launch, but even on Winix’s own site you can now find it at the reduced price of $279.99 – placing it firmly in the mid-range realm of air purifiers. It's also often subject to further price cuts online, moving it closer to the $260 mark, so it's a good idea to shop around. 

Winix HR900: 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. 

Winix HR900: specs

Filters: 5 - Ultimate Pet Pre-filter, pre-filter, Activated Carbon filter, True HEPA filter, Winix PlasmaWave ionizer
Ionizer: Y
Auto mode: Y
Max power use: 46.6 watts
Noise: 55.2 DB
CADR: 194/200/220 (smoke/dust/pollen)
Coverage (sq ft): 300

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.

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.

The team also praised the quiet and soft sound of the fan, which meant that any noise it did make was barely noticeable.
