PUREBURG Replacement Filter Compatible with LG PuriCare AeroTower U9C Series U9CV2B U9CS1C U9CV1C Air Purifying Fan,H13 4-Stage Filtration Activated Carbon Air Clean

Works like OMF filters

Don't have to buy the expensive filters from LG anymore. This one works just as well.

Fits great for cheaper

Looks almost the same quality as LG genuine filter This filter is slightly smaller in diameter compare to the LG filter and this causes it making noises when the Aero tower set high 7 and above

I've read that some of these replacement filters don't fit snugly enough to trigger the UV light. This one didn't feel -quite- as tight as the OEM LG filter, but it's still a solid fit. I have two LG AeroTowers and when I run diagnostics on them, both indicate no problems. So it seems like the UV functionality is active. Put side-by-side with the LG filters it looks about the same otherwise, size-wise. These are significantly cheaper than the LG-branded filters. If they're still listed with Amazon when it's time to change them out again in a year, I'll get another pair.

While it fits in my LG tower air purifier, it is not as snug as the original LG filter. It may need to be replaced soon because it consistently lists the air quality as lower than when I used the LG brand filter.

Seems good. looks similar to OEM.

Clearly the LG air purifier works well these filters.
