To remove as many impurities as possible, air goes through three filtration stages before it is released back into the room.

1.Fine preliminary filter – this is where bacteria, pet dander, mold and fungi are trapped. It is located on the other side of the true heap filter.

2. True HEPA Filter – this filter tackles dust, mist, large particles and pollen. It removes up to 99.97 percent of these pollutants.The HEPA filter traps contaminants as small as 0.3 microns

3. Activated carbon filters – This filter takes care of lingering odors around the house including tobacco, smoke and cooking smells.

Air quality indicator

levoit air purifier reviews

The automatic sensor adjusts the air purifier’s fan speed according to the current air quality.

An integrated air quality indicator uses different colors to tell you how clean or dirty your indoor air is.

Red color means dirty air, yellow color means moderately clean, green color means the air is clean enough for breathing while blue which means air is very clean.

If you start cooking something or your pet makes a mess on the litter box, you’ll notice the light turning to yellow or red.

You’ll also hear the fan pick up speed as the air purifier tries to clean up the air.

Ozone free

Air purifiers that generate negative ions to sanitize the air also produce some Ozone, which is not so good for your health.

The LEVOIT LV-PUR131 Air Purifier is 100 percent ozone free. This makes it environmental friendly and safe to use.

Large space coverage

levoit air purifier reviews

The LEVOIT LV-PUR131 Air Purifier is designed to cover medium and large rooms. It can quickly (less than 10 minutes) clean all the air in a room of up to 322 square feet.

It’s great for living rooms, bedrooms, home offices and nurseries.

Automatic shut off mechanism (Timer)

The timer allows you to programme the air purifier to run for up to 12 hours.

This saves you the trouble of having to keep switching the air purifier on and off especially during the day when activities like cooking pollute the air.

 The timer is also great for nighttime use. If you don’t want to leave it on all night, you can set the timer for a period like 5 hours.

The main limitation of this air purifier is the too-frequent air filter changes.The filter is supposed to last 6 months but often lasts for less time.

If you live in an area with lots of pollution (e.g. during wildfire season), you might have to buy a new filter every 2-4 months.

 But at least the filter replacements are not too pricey.


Dimensions: 14.5 x 7.2 x 18.5 inches

Weight: 11.24 pounds

Shipping weight: 15 pounds

Coverage: 322 square feet

LEVOIT LV-PUR131 Air Purifier for Pets Review

If you have a pet at home, it’s challenging to find an air purifier that actually works. This is especially the case if you have allergies and are very sensitive to pet fur and dander.

The LV-PUR131 works as advertised. Using an efficient 3-stage process, which includes HEPA filtration, it removes common allergens and pollutants including the extra-tiny ones that escape most purifiers.

You do have to change the filter often but it’s a small price to pay for clean allergen-free air.
