Air Purifier Replacement Filter Compatible with Freshpro KF-P34W, 4-in-1 True H13 99.97% HEPA filter, Fits KF-P34W Air Purifier, 1 Pack

Great filtration system.

Remodeling and it works hard all day and by evening the air is clean.

Air quality in Tucson, AZ is terrible during certain times of the year Dust gets everywhere inside and outside, especially during the Monsoon season which comes sometime between July and September Having these air purifiers inside will greatly reduce dust and pet-dander that collects over everything on a daily basis Time will tell, so if they do the job correctly, then I will purchase an additional two more So far, they seem to be working fine

I needed a replacement filter for my air purifier. This one does the job it was designed to do. I've only had it in the system a day or two, but everything is working nicely. An air purifier is only as good as the filter in it, and this one is working just fine.

Pretty simple product, a replacement air filter. I had no problems with this at all. Packed securely in it's box, easy installation, and works well in the unit. Very easy recommendation.

Great replacement filter for my air purifier!

I figure since these usually last at least a few months, the cost divided by the longevity of clean air is a wonderful value, and the health benefits to my children make it priceless anyways. Dust (busy highway/dirt driveway), dander (cat) and seasonal allergens (nature) is a huge problem (especially for my asthmatic), and these filters work so efficiently that my air purifier is always blue, which means good quality air on my machine. I Trust the HEPA brand filters, and it’s always comforting to have a brand new one installed and immediately at work keeping my kid’s breathing air safe.
