If you need a good air purifier for mold, like the AeraMax Baby DB5, you might be interested in the Levoit LV-PUR131S. In fact, the pre-filter specifically targets mold. For your bundle of joy, you’ll love turning the Levoit air purifiers to Sleep Mode, a must-have for top-rated air purifiers even for baby rooms.

Why We Like It – LEVOIT LV-PUR131S

The Levoit LV-PUR131S is perfect for stepping into the world of cleaner air, thanks to its modern features like Auto Mode, Wi-Fi connection, large coverage area, and excellent pricing.

  • Handles large rooms as big as 900 square feet
  • Low filter cost for replacement filters
  • Affordable pricing
  • Motor can get hot occasionally

Power & Speed

To get a sense of its power and speed, you need to know its ACH and CFM. The Levoit LV-PUR131S has an ACH of two, meaning it’ll filter out the air around you twice an hour. Its CFM, on the other hand, is 131, which is a bit on the weaker side, but still good for smaller rooms. But for a unit that handles larger rooms, you’ll want to check out the Oransi Max. It’s a great air purifier for getting rid of mold.


With its speed and power, you can purify a room as large as 900 square feet in an hour. Of course, there are diminishing returns the bigger the room, so the LV-PUR131S is better at filtering a room as big as 500 square feet. However, the Alen BreatheSmart Classic Large Room Air Purifier is more comfortable with handling large areas. If you have much smaller rooms, then you should go through our Levoit LV-H132 Air Purifier review for a compact


Where the Levoit LV-PUR131S uses three filters, the Rabbit Air Minusa2 has six filters, but is still efficient nonetheless. It improves air quality with three separate stages: the pre-filter, True HEPA filter, and the activated carbon filter. The pre-filter captures mold, fungi, pet dander, even dust, and other large particles; the HEPA filter handles particles as small as 0.3 microns (like dust pollen), and it’s 99.97% efficient; and the carbon filter handles smells from food, smoke, or even pets.


The Levoit LV-PUR131S has some good sturdiness. It weighs just under 12 lbs, so it isn’t exactly light, with soft padded feet to keep from scratching floors. It’s relatively small, but taller than it is thick. It’ll fit comfortably against or near a wall.


To find True HEPA air purifiers this affordable, like the Levoit air purifier that can handle large rooms, and has relatively low-cost replacement air filters is like finding a needle in a haystack. You are absolutely getting an amazing deal here. And the VeSync app adds a bit more value for creating schedules. You could go cheaper with the SilverOnyx Air Purifier, but it’s been reviewed less than the Levoit LV PUR131S Smart Purifier. If you are tech-savvy then you may want to check out our Levoit Smart Wifi air purifier review to get an air purifier with Wifi connectivity and Alexa voice control


The Levoit LV-PUR131S sets out to impress, and it does. Several times over, in fact. It gets a bit hot, but keeping it clean should circumvent that. It handles up to 900 square feet, it’s affordable, and so are the filters. Where else are you going to find an air purifier that does as much?
