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

It’s the same size, shape, and weight as an official replacement. It does just as good of a job.

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.

Best . Last 6 months.

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

quality build, exact fit but overly expensive

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.

Look, I am ALL for saving money but folks buying aftermarket filters are stupid. $20 for a “filter” from a company who could be using cardboard as a filter for all you know.....my lungs & allergies are too important to blindly trust a non OEM filter. But to each their own....those reviews may be good but people are missing the bit where they’re buying filters more often.This filter is the heart of the unit and what makes it work as intended. I love my Levoit purifier for many reasons other than because it works....but I know it works because of their filter. It does what it says & lasts forever. And I burn candles daily, have a dog & crazy desert allergies. It’s so nice to be able to breathe & breathe clean air in my home.***Jan 2022 Update:I run my unit 24/7. There is soo much dust & airborne crap in Vegas you wouldn’t believe. Between smoking & candles…this filter does what I need.They REALLY need to add a filter for pets, toxins & smokers like they do for the smaller units. My smaller unit - with the smoke filter - works in conjunction with this filters larger host to capture all the crud in the air. This filter lasts me 6-8 months before needing to replace it.

As someone with severe allergies, I occasionally enjoy opening the windows for a refreshing breeze. This has greatly improved the air quality within my apartment. Additionally, it's beneficial for being near my cat's litter box. I've noticed that the air purifier switches to high filtration mode whenever he's nearby. This made me realize that his litter was not only unpleasant for him but also affecting me adversely.
