PUREBURG Replacement Filter Compatible with LUFTRUM & Loniko AC400 Air Purifier, H13 True HEPA 3-Stage Filtration Activated Carbon Air Clean Dust VOCs Odor

Great cost for a great filter. Works great even with 2 large dogs in the house.

Works great but expensive purchase every time!

I’ve been using these filters for a few years now and I am very pleased. I use to buy the much more expensive ones that originally came with my air purifier but after trying these I never looked back. They fit perfectly and provide the exact same air quality as the pricier ones. I have them on auto delivery now. Save yourself some money. These work.

I love this machine and the filter. It’s very dusty here in the South and it keeps the house air quality nice and clean.

These filters are wonderful and are a perfect fit for my LUFTRUM air purifier. The price point is a bit high but lower than the LUFTRUM price. I’ve compared them side by side, I see no difference but that is only visual. I am hoping it is the same quality.

Looks close to the stock OEM filter on the LUFTRUM AC400 but sells for around half the price. The stock filter lasted around 6 months or so for me. Biggest difference I can tell from looking at them is this one doesn't have a layer of foam tape on the sides to provide better air sealing for the fan. Otherwise they seemed identical. For the money this is a decent price for a air filter. Most filters in this class are pretty pricey unfortunately.

Just like the original for half the money

I'm very happy to see that Pureburg has released a less expensive alternative to the ridiculously expensive filters from Luftrum for their AC400 Air Purifier. It appears to be nearly identical to the OEM filter and fits perfectly. Pureburg claims their filter captures "99.97% of airborne dusts PM2.5 down to 0.3 microns in size" while the Luftrum claims to "filter 99.99% of airborne particles such as pet dander, dust mites, and pollen particles as small as 0.1 microns". I don't know if this would make for any noticeable difference in performance. I'd been running the original filter for well over a year and the new air filter subjectively seems to be doing a better job than the really old one.
