PUREBURGAP350F Replacement Filter Compatible with Envion Allergy Pro AP350 Air Purifier, H13 HEPA High-efficiency Air Clean Dust 1-Pack

These filters are great when the unit needs to be changed. Actually, that's a feature of the air purifier rather than the filter itself. But if you have one of the purifiers this filter fits they are great and good price too. Just be sure to do it outside. They work so well they're filthy when you remove them.

I rediscovered a 12+ year old TPP300D in storage and powered it on. I was fairly sure it’s been discontinued and wasn’t wrong. It’s a shame to throw out a perfectly good machine and this brings me to this page. Out of faith in S’s review I purchased this substitute and can verify that it fits perfectly in my TPP300D air purifier (which clearly needed a replacement).

I believe this replacement filter works as described. It fit perfect into my Allergy Pro. Due to the high level of dust in my desert environment, this filter seems to help keep the air clear and my allergies in check. Helps eliminating the kitchen odors too. Not cheap but worth it! Will purchase again.

There were many to choose from but not all had info to be sure. It was. The LifeSupplyUSA that had the proper fit was shipped in a cardboard packaging that was soooo tight that I had to tear it apart in many places to get it out!!!This PureBurg had no problem and looks Identical!

I like how affordable this filter is. I've had mine for a little over a month and the quality is just as good as the stock filter that came with my air purifier. I will continue purchasing these

It fits perfectly in my Envion Allergy Pro. It filters well - when I replaced my previously ordered one after months, it had caught a lot of dust. It doesn't have a smell after the initial hour or so.

It works great!

It fit my model and seems to be off equal quality as what the manufacturer originally installed.

This is the second time ordered filter, a lot more economical then from manufacturer
