PUREBURG AP450F Replacement Filter Compatible with Envion Allergy Pro AP450 Air Purifier,H13 HEPA High-efficiency Air Clean Dust 1-Pack

This is a great air filter. We have been using and vacuuming our old filter until it started to fall apart. We are so happy to have found this replacement online at amazon. It seems to be the same a s the old one. We love it because it definitely removes the dust particles from the air at night and my allergy prone wife has stopped coughing and sneezing and sleeps instead.

Bought this filter to save $. Noticed right when I took it out it did not look like the original or weigh the same. It fit perfect, but is not the same weight as the original. Anyone who has replaced this filter from the original knows what I'm talking about. Because of this, I'm not sure it's a true Hepa filter. Will not order this again. Will buy the original next time.

Filter fits perfectly. This is my second time purchasing a replacement filter on Amazon, however my previous purchase was from a different seller and it did not fit correctly. This one fits just like the original. I will be purchasing from this seller again.

I looked at all the different kinds of filters that were supposed to fit in my allergy pro machine and this one almost matched the size. It works great will get another to have on hand

High quality, and will do a great job. Great value.

I dislike that the filter did not have two sides. I needed to clean a lot more often.

as described, this filter fits perfectly. it may be expensive, but it should last a long time, at least a year.

Fits perfectly. Works great!

Great item, well worth buying , will be getting another one soon, does the job for less the price.

It's a high quality filter and it fits inside the air purifier that it supports.

Good substitute for original

The filter rescued my family from recurring breathing problems . Delivery took far too long and the filter is very expensive for my budget. However, it was much needed.
