WOW It's so white! You can tell how dirty the old one was.

They work well, & are the right ones for the unit.

I’ll give these replacement filters a solid B plus they would’ve gotten an a but sadly they’re a little bit pricey. If you take care of the filter that came with the machine wash them thoroughly with warm water and then let them dry naturally you can very easily keep using them longer.Besides the the cost so far, I see that these filters have been working well

I bought the Therapure air purifier from a big name wholesale company about three -five years ago. I vacuum the filter clean as instructed often but with two dogs and living in a rental with terrible seals around it’s screens and windows, I’m having to vacuum so often that the filter really needed replacing. I had a hard time finding it in what I thought would be obvious place to look. It was not in that big name warehouse nor was it online with them or at any of the local home improvement stores. I was shocked/happy to find this on Amazon. I bought two sets. I replaced the filter and have three left. Now I hope the air purifier lasts long enough to use all four filters!🤣. I was hoping for a cheaper price as I hate when the filters cost goes over the total price of the unit. Once the filters are used up, I will buy a new air purifier.

We tried other cheaper brands for replacement filters and this is the only one that fits snug like the original filter. Easy to replace and helps keep the dust in our bedroom to a minimum. Hope these last just as long

Early arrival and perfect condition.

Everywhere I looked I had a hard time finding a replacement filter for Envion Therapure tpp630 model. But after some research gave this a shot. It does fit the tpp630, even though, it does not say this model number in the description. Now, it has been a while since we changed our filter but after swapping it out, the filter works and now the air purifier is extremely quiet when on the lowest setting. We are very happy with this!
