Air Purifier Replacement Filter Compatible with Levoit Core Mini Air Purifier Filter 3-in-1 H13 True HEPA Filters High-Efficiency

These filters were a perfect drop in replacement for my Levoit Core 300. I leave my filter on 24/7 so I end up changing out the filters often. I found these filters to feel high quality with thick filter materials and would recommend these. I would like to point out though, and this isnt factored into my rating, is that the filters came shipped in a thin paper box which was falling apart by the time it came to my house. I would have expected it to come inside another box, so double check that there isnt any damage just in case. Even though the box was damaged, the filters were perfectly find and after installing one into my filter, I can report that there is no weird off-gas smells or anything like that. The old one went out, the new one easily swapped in, and my filter was good as new. Because this filter is pretty popular, you'll find a lot of off brand filters and so far I found that every single one of them were good. So as I usually do, I recommend buying the filter that has the best deal at the time that you're buying it. If that happens to be this filter, I dont think you have anything to fear. Read more

I’ve been using these Levoit Core 300/300S compatible filters in our air purifier, and they’ve worked very well so far. In fact, the build quality seems higher than the OEM filters I most recently received. The foam gasket on these is noticeably nicer, creating a better seal, and aside from that, I honestly couldn’t visually tell them apart. They’ve been in use for a few weeks now and are holding up exactly as expected. Based on how they look and fit, I’m confident they will last at least as long as the OEM filter, if not longer. Overall, these feel like a great value and a reliable alternative to the branded replacements. ✅ Fits the Levoit Core 300/300S perfectly ✅ Better foam gasket than OEM ✅ Solid construction and filtration performance ❌ None so far Bottom line: A high-quality, well-made replacement filter that matches or exceeds OEM quality at a better price. Note that in the attached photo comparing the foam gaskets, this product is below the OEM filter. Read more

These filters look and fit just like the original OEM filters. Time will tell if they capture as much but the look and feel is OEM quality. They are a much better deal than brand new filters every three months, but at this cost I can afford to change my filters more often. They have no effect on the noise level as that is more a function of the unit itself and not the filter, but there is no noticeable increase or decrease in noise. I was using the OEM filters that I would blow off and reuse, that works for a while but I think I will stick with these for a while as they are functional. Read more

I have a Levoit Core 300 air purifier. I found that this Unikyy Air Purifier Replacement Filter fits a little more tightly than the filter it came with, and was slightly more difficult to insert. This is not really a problem - I did manage to get it in pretty quickly. Just expect that it's not going to be quite the same experience and you may need to use a little more force and repositioning than you're used to for insertion. Beyond that, it works with no apparent issue. There is no apparent change in air output or noise levels, and the outer filter collects dust similarly. The big question is whether it filters as well as the name-brand replacement filters, and unfortunately, this is something I have no way of testing. But for around half the cost of the official replacement filters, they seem to work well enough for my purposes. Read more

These filters are nearly identical to the LEVOIT option, but at about $11 per filter these are less than half the price of OEM. They have the same shape, size, feel of similar quality and materials, and install just as easily. They work fine in our Core 300 purifier. The only part I can't objectively test is whether the air is cleaned just as well. However, our priority is removing "larger" particles like pollen and dust which cause allergies, and we don't have a need for a medical-grade purifier that would filter out bacteria/viruses. For our needs, these work great and reduce the cost of replacement filters significantly. Read more

I installed this Unikyy replacement filter in my Levoit Core 400S and the process was simple from start to finish. The filter arrived well packaged and in excellent condition, with no damage or loose material. It fit into the purifier housing securely and aligned exactly like the original Levoit filter, so installation only took a few moments. The purifier has continued to operate smoothly since the replacement. Airflow and sound levels are unchanged, which indicates that the filter is working as intended. The materials feel solid and well assembled, and the overall quality seems consistent with the original filter. Although I cannot yet comment on the activated carbon layer, the construction appears reliable. Read more

So if you got a Levoit core mini on a Prime day sale, then these fit exactly like the ones that come with the purifier. This one fit mine perfectly. I did a test fit, and turned it on for a bit and it seemed to run exactly like the one that came with it. These are priced well, you get two for the price of one branded one. This doesn't make any extra noise or anything in the purifier. It seems like these are a good deal. If these cause problems over the long term I will update this review but based on my initial tests, these seem like a fully functional filters. Read more
