Small purifier with a big punch

[This review was collected as part of a promotion.] This purifier is a compact, lightweight option that works especially well in bedrooms, home offices, and other small to medium spaces. The build is great and gives a sense that it will last a long time. The biggest is that the filter captures up to 99% of microscopic airborne allergens and particles such as dust, pollen, and pet dander. The maintenance is simple by just replacing the single filter. This is a solid choice if you want a simple, compact HEPA purifier without paying for a lot of smart features. Its quiet operation, small footprint, and straightforward controls make it particularly appealing for bedrooms and offices.

Great air purifier

[This review was collected as part of a promotion.] This is a great air purifier. It was easy to set up and so easy to use. I appreciate the functionality and sleek look. I feel like it does a great job of pulling allergens out of the air and my sinuses are already doing a lot better. We have two dogs in the home so the pet dander can get a bit much sometimes but this appears to be clearing it all out in the small living room it is placed in. I would absolutely recommend this product to others. I believe it is well worth the money.

Clean air

[This review was collected as part of a promotion.] The purifier is very effective in cleaning the air and removing odor from cooking and etc. it was very easy to set up and I didn't need the manual to actually put it together, although it can be helpful if you need one. I love how you can change the power and put a timer. It works great and love it!
