LEVOITLV-H133 Replacement Filter, Genuine Air Purifier Filters, High-Efficiency Activated Carbon for Removal of Smoke, Odor, Allergens, Pollen, LV-H133-RF, White,1 Pack

I've been using these for a couple of years to help with cat fur and litter dust and the filter still works great. The replacements might seem pricey but really comes out to like ~$10/month and the cleaner air is worth it.

I like the air filter, this is the third filter replacement I’ve bought. I usually vacuum it out once and use it another few months before replacing it. Works great!

UPDATE: Extra stars for the excellent customer service I received directly from Levoit. They were very responsive to my email inquiry about the bad smell situation. They seemed really concerned and asked a lot of questions to understand exactly what was going on and come up with the best solution. I am very happy with the outcome. Thank you, Levoit, for your five-star commitment to your customer's needs.ORIGINAL ONE-STAR POST: I've changed my Levoit air filters regulary since I purchased my unit in 2020. This filter is poorly made compared to my previous filter -- even the seam is off center -- and it has THE WORST chemical-like odor coming off of it that is sickening!! In the last five years, I've never had this issue before!! Their quality has gone down hill. I need to research for a new air filter. Ugh.

Perfect fit for our air purifier. Its very heavy and sturdy so I know its serious.

Does the job as intended. It works well in large, open spaces like my living room.

I've got multiple cats at home which can, if not careful, make your home smell. I have multiple air purifiers around my home which help maintain a clean and fresh smell in my home such that many guests comment on the fact that I have a clean smelling home with multiple cats. This air purifier filter does the job at an affordable price.

Best . Last 6 months.

Installing the product is really easy, and on the automatic setting, I find one filter lasts me about 1 year. I know you're suppose to change it a bit more frequent than that, but I found the filter just lasted that long :) Really makes a difference in my home with two cats! Friends with allergies will come over, and they say their allergies aren't as bad compared to other homes with cats they've visited.
