Review: Good filters. Do not buy desertcart Resale, only buy brand new - I use these filters with my Levoit 400s. These genuine Levoit filters are good at removing odors and dust. I highly recommend removing the filter once every month to check for dust buildup. There is a high probability you will need to wipe off the outer dust buildup every 1-3 months, but it does depend on how dusty your space is, and at what fan speed you use your air purifier at. To clean the dust, use a dry cloth. The dust comes off really easy. As for removing odors, the filter does a very good job. However, be aware that, how long the filter lasts depends on how much smell/smoke you're pulling from the air, and how often the air purifier is running, and at what speed. I use this in my bedroom, no smoke and no strong odors, and it runs 24/7, and when I run this on auto or at the lowest fan speed, I usually get six months before the filter begins putting out a certain smell that lets me know I need to replace it. You may need to replace yours earlier or later. It all depends on the factors I mentioned. Overall, very good filters, but also very expensive, and not great for the environment to be throwing one of these out every six months. Before COVID, this filter was priced anywhere from $29 - $39. Nowadays it fluctuates between $39 - $49. If I can catch it at $39 or less, I usually try to grab as many as I can. As for desertcart Resale, be careful. I have purchased acceptable, very good, and like-new condition. All three conditions came in the original box, but the plastic bag that seals the filter was removed. This isn't good because then there is no way to tell if the filter was used. Someone could have used the filter for some duration, and then wiped off the outer dust layer, and the filter would literally look new, and so there would be no way of knowing if it was used and for how long. In my opinion, desertcart shouldn't be selling these filters if the factory sealed plastic bag around the filter has been opened My advice is to only buy new filters so you can be sure they are fresh, new, and never used.
Review: Excellent filter - Filter works great.My husband has a home gym in the garage and has this large Levoit air purifier.This filter works great when the light indicates it needs to be replaced.The filter has helped with allergies and keeping the garage air quality better.Noise is minimal,the filter lasts a long time more than 6 months or so can’t even remember last time changing, the size is bigger than what you would put in a bedroom.Good for larger spaces.Will continue to buy filter for Levoit Purifier and would highly recommend.

## Questions & Answers

**Q: Does this get rid of weed smell?**
A: By eliminating airborne particles, it does provide some relief, but the off-gassing from these particles isn't fully addressed. The filters contain only a limited amount of activated carbon, which eventually becomes saturated.

For instance, my bedroom air purifier effectively filtered out wildfire smoke particles down to one micron, but it still emitted a smoky odor. 

In contrast, my higher-end air purifier on the main floor boasts 780 cubic inches of activated carbon, preventing any unpleasant smells from escaping. It took about a year and a half for the carbon to become saturated.

In conclusion, while such filters can certainly help reduce the number of free-floating particles, they may not be entirely effective in eliminating odors.

For the price, you will notice a great improvement with air quality however.

**Q: how often must filter be replaced?**
A: Depends on how much you have it on and at what speed you keep it on, along with the size of the room. Best way to find out is to use your device starting with a fresh filter and see how long it takes for it to need a new one in your space. Could be 3 - 4 months, more or less. It really depends.

**Q: Are these washable/reusable?**
A: The instructions mention changing them when indicated by the unit.
It does not mention cleaning and recycling the filter.
As they have multiple filter screens, depending on what they are filtering (chemical fumes or dust) I would generally interpret that as no. 
Mine has just indicated to change the filter as I use it for chemical fumes from 3d printing.
The HEPA filter does a good job here, so I will change it.
They are expensive,  this one lasted for 11 months with the machine set to Auto with the occasional fan setting of 3 when it needed it.

**Q: Can this filter be washed by hand?**
A: Seems like only the one made for pets is washable but then I think it's only the outside screen part that is removable and washable. The inside of the filters appears to be made of something like cardboard which will get wet and mold will grow before it has a chance to dry

### ⭐⭐⭐⭐⭐ Good overall purifiers and filters!
*by H***O on July 26, 2025*

I have 4 Levoit air purifiers in my home. One 400S Three 300S. I like them all andvthey all work well, especially the 300s in the bedrooms and the big 400S in the kitchen/den area. They do a great job with the dust, dander and pollen. The odor elimination could be better, but it helps and eventually gets the odors out. It just takes a while.. I continue to buy the Levoit branded filters because they fit well. They’re high-quality but I do feel like they’re a little bit pricey. Giving them a quick brush every month helps with their effectiveness and longevity..
