If you’re a pet owner struggling with allergens, dander, or lingering odors, Levoit Core 300-P Air Purifier might be exactly what you need. Thousands of verified buyers say this affordable air purifier has transformed their homes. Here’s what real users are saying.

You’ll Notice the Difference Fast

Most people feel a difference within just a few days. One reviewer said, “Within just a few days of running it, our family felt a huge difference—no more stuffy noses.” Another user who suffered from morning allergies shared, “I used to wake up a lot with a stuffy nose, and I don’t find that happening as often since I got it.”

After 10 months of use, this filter shows how much dust and pet dander it captures.

Great for Homes with Pets

Pet owners consistently praise this purifier. One reviewer with two large dogs said, “I have 2 large dogs and a very old dusty house. My filter light came on after 10 months of use. It has helped get rid of bad smells.”

A husky owner reported, “We have a husky and she sheds a LOT. We have had this air purifier for 2 months now and our air is so much cleaner.”

Multiple users with cats noted it eliminated litter box smells. One person said, “I bought one for my bunny’s litter box, and before this purifier, I constantly sneezed. Once I started using it, the sneezing completely stopped and the smell disappeared.”

Works great in homes with cats and dogs.

How Loud Is It?

On low and sleep mode, it’s very quiet. One reviewer said, “We run it 24/7 in our bedroom, and it’s just a gentle hum that we don’t even notice.” Many users say it actually helps them sleep better because of the white noise.

The high setting is louder, but most people only use it when they’re not in the room or need a quick boost.

Room Size and Coverage

It works best in medium-sized rooms (12×12 to 20×20 feet). Users in bedrooms, living rooms, and even college dorms report excellent results. One parent sent it to their son’s dorm: “Within 30 minutes, his roommate said ‘whoa, it feels so much better in here.'”

Compact design fits easily into any room.

Filter Maintenance

You’ll need to replace filters every 6-8 months depending on use. Between replacements, you can vacuum the filter every 1-2 weeks to extend its life. One reviewer explained, “I vacuum the filter about once a week with a hose attachment and so far, so good.”

Replacement filters are reasonably priced on Amazon. The standard filter works great, but there are also specialized filters for pets, smoke, and toxin removal.

The dusty filter proves it’s definitely working.

Easy to Use

Setup takes about 2 minutes. Just remove the plastic from the filter, plug it in, and you’re done. The touch controls are simple with three fan speeds, a sleep mode, and a timer. You can even turn off the display lights at night.

One blind reviewer noted, “I’m totally blind, but find it’s not too hard to operate without seeing it.”

One reviewer said, “I have a cat and I also smoke inside. Literally none of my friends knew I smoked inside until I told them.”

• Vacuum the outer filter weekly or bi-weekly to extend filter life
• Use sleep mode at night for quiet operation with lights off

• Consider buying multiple units for different rooms

Important Note

One reviewer had an issue using it overseas: “If in your area a voltage of 220-240V is used and you do not have a voltage converter, the device will be burnt.” Make sure you have the right voltage or converter if you’re using it outside the US.
