    Great filter, great customer service

    Product works very well. We have two constantly running in our home where we have 3 cats and 2 bunnies. Customer service is prompt and very helpful. We have been on the recurring filter subscription for almost 2 years now.

    Works well

    We have five dogs and a doggie door for them. During the day they have the freedom to go out and in as they please. They roll in the grass and dirt so that dirt is in their fur and it is brought in frequently The purifier is near the door so the filter .gets dirty quickly. Husband and I do have slight allergies from the dander. I would like to shorten the time when we change the filter by two weeks

    Cool

    To my surprise the PuroAir is telling me the air quality in my apartment is great. I will keep enjoying this product for my peace of mind. I purchased the PuroAir for concerns I am having with my dogs health. He may have bronchitis due to all the dust that's is the apartment. Knowing air quality is good is one thing I can cross off my list with trying to keep him healthy.

    Highly recommend

    The best purifier for my house with both a dog and a cat. The difference in the air quality is evident and since I have begun using this air purifier my allergies have been better controlled.

    Gets the job done!

    These purifiers just quietly do their job. My air stays fresh. Very simple to use. Filter replacement is a 30 second process. I have had them for over 2 years without a moment of trouble. They work through our nasty wildfire season - the AQI was over 1300 on several days but inside my house it was just fresh air. I highly recommend them.
