Five Stage Filtration

Washable pre-filter will catch pet hair and other big particles. Washable Advanced Odor Control carbon filter will make sure lousy odor from pets is removed. It can also successfully remove other types of odor. Ultimate pet prefilter is another layer in this system that removes pet dander, hair, and other large particles flying in the house.

The True HEPA filter is the fourth layer of defense against nasty particles. True HEPA is also the most important filter in the system. The last pet pollution destroyer is Plasma Wave Technology. Plasma Wave Technology breaks particles, odor, allergens, and other pollutants in the room on a molecular level.

AHAM verified that Winix Ultimate Pet air purifier is best used in 300 square feet room size. In such a room, it will perform best and remove pollution at best performance.

Smart Sensors

Smart sensors are a big part of Winix HR900. These sensors help air purifiers work at an optimal speed. Dust sensors detect air quality in the room and adjust accordingly. There is also an odor sensor which helps air purifier remove odors at a fast speed.


Winix HR900 air purifier is not small, and you will need to find a proper space for it in the room. But thanks to the excellent design, you can place it in the middle of the room, and nobody will mind you.

Prevents Allergies

Many people are allergic to pet pollution like pet hair or pet dander. With Winix HR900 Ultimate Pet, you can be sure that this type of pollution will be removed from the air.

Best for Pet Owners

With Winix HR900, you can have pets running through your house without a problem. The air purifier will make sure your home stays fresh and without pollution. Even if you have an uninvited guest by turning Winix HR900 on, nobody will know you have pets in the house.

Silent at Work

If you are looking to use this air purifier in the bedroom, I can highly recommend it. It has a silent mode, which is quiet as a whisper. Even at such low-speed air purifier will make sure the room is filled with clean, fresh air. In such a room you can have the best sleep.

Auto Mode

Winix HR900 has sensors for dust and odor, which can be used for automatic speed adjustment. With such mode, you are letting the air purifier decide speed based on pollution in the air. This mode can save energy in the long run. In the bedroom, while on auto mode, the air purifier will turn off light thanks to light sensors. However, it will stay in auto mode, which means it could still use turbo speed if the pollution in the room is high. If you have problems with sleep because of the noise, then choose the sleep mode option.

Price and Filters

Price is another great advantage of this air purifier. For such an affordable price, you are getting a powerful air purifier with five layers of air filtration and smart sensors. You won’t find those things in many other air purifiers in the same price range.

Filters, however, need to be replaced regularly, especially carbon filter, which needs to be replaced every month to make sure pet odor stays undetected. Other filters are washable, and the True HEPA filter has 12 months lifetime depending on the usage. When replacing filters, always make sure you have proper filters for your machine and always buy original filters. Only by purchasing original filters, you can be sure that the air purifier is working at best.
