Very quiet operation. This air purifier comes with the cylindrical design concept, together with the same smooth flowing curves, and same 360° air intake grill like the Core 300 model. It’s Levoit’s marginally better answer to any other low-end air purifiers, and they’re proud to keep that on Levoit Core P350.
- Breathe Quality
This mid-size Levoit hits that sweet spot between a small tabletop, personal purifier, and a larger floor-based purifier. You can use the P350 in either application due to its versatile size. The overall performance of the Levoit Core P350 was pretty impressive. This purifier is compact, efficient, and did great job of purifying the air.
- Modern Castle
If you’re looking for an affordable air purifier to remove pet dander, hair, and odor particles in a small room, this is a good model to consider. With a 360-degree air filtration design and filter, the Levoit P350 has 40% more efficiency than air purifiers that use a standard flat filter.
- Home Air Guides
The motor itself is fairly powerful for the size. It utilizes an AC capacitor and a high-precision bearing. This ensures a long life, with minimal wear and tear even with intense, constant use. The 360-degree air intake is very effective at drawing in air from throughout the room. Even at the highest speed, the Core P350 produces only 50dB of sound. This is quieter than a normal, indoor conversation. In addition, you also get a pet/child lock button.
- Nerd Tech
One of the most outstanding products with the capability of capturing pet dander in the air. Don’t let the size of this air purifier fool you. It’s so efficient and can remove 99% of air pollutants at home or the office. The cylindrical-shaped air purifier is perfect for your office or home, thanks to its design. You can place the air purifier by your bedside and sleep all night, confident that you are breathing in clean air. Advanced pre-filter and carbon filter.
- Reviews of Air Purifiers
At the lowest setting, the device will produce noise levels of 24 dB, which is well below average and will allow you to sleep comfortably. Another contributing factor to your good night’s sleep is the possibility to turn the lights of the unit completely off. No second-hand pollution – all the dander and dust is chemically decomposed inside the unit.
- Homeair
Low-cost option tailored to pets. Contains a HEPA filter for pet dander and a carbon filter for pet odors. Runs quietly.
- Healthline
Has a Pet Lock that prevents the change of settings by pets or children. It can cover up to 219 square feet and has a 3-stage filtration system (fine preliminary filter, true HEPA filter and activated carbon filter) that captures up to 99.97% of particles (0.3 microns) in the air. It’s effective in absorbing pet odors and decomposes them to avoid second-hand pollution. You can set a timer for 2, 4, 8 or 12 hours.
- Earth's Friends
No doubt, LEVOIT Air Purifier Core P350 is an excellent air purifier and one of the best least expensive air purifier. Basically, it is a pet allergic model. You can use it if you have pets or you have pet allergies. Filtration System: It has a 3 stage filtration system like other classic air purifiers, but with small changes. It has a 360-degree airflow to give you purified air in every corner of the room.
- What Air

It’s equipped with the carbon filter ARC formula that absorbs the odors and chemically decomposes them so they cannot air-born again and again. Its also the most recommend solution again second-hand pollution.
- Smart Brainy Homes
What experts didn't like
No Smart Sensor. Is slightly more expensive than older model.
- Breathe Quality
Feels similar to the Core 300, but with a higher price tag. No real-time air quality detection or readouts. No “Auto Mode”.
- Modern Castle
The Levoit P350 air purifier doesn’t come with a ton of advanced features.
- Home Air Guides
You might prefer a more powerful filter. 219 square feet is sufficient for one or two rooms. But to treat an entire floor, you’re going to need more power.
- Nerd Tech
Sadly, the air purifier does not have a small footprint. According to the manufacturer, the dimensions of the air purifier are as follows – 8.7 by 8.7 by 14.2 inches. It weighs 7.5 pounds or 3.4 kilograms. Due to its size, the air purifier is not perfect for travel. The air purifier does not have remote or app connectivity.
- Reviews of Air Purifiers
A little downer is a fact that the purifier supports the only 120V/60HZ. This means that if you want to use it outside of the USA – in Australia, for example, you will need to get a transformer. Since the unit is still new, an Energy Star test has not been done, so this is not an Energy Star appliance.
- Homeair
Not Energy Star certified.

An Overview On Air Purifiers

The reasons for buying an air purifier can be as numerous as the number of pollutants in the air — and indoors, that number tends to be bigger than most people would expect. Despite the best efforts of the filters in our air conditioners, pollen and dust particles can settle into carpets and upholstery. Mold spores can grow in moist areas. And if there are pets or smoke involved, expect dander and carcinogens to be part of every breath.

Whether you suffer from allergies or just want to eliminate the smell associated with all this particulate matter, a good air purifier can be an essential accessory in any room. But how are they different from the filters we already have in our regular AC?

All that depends on the purifier. Most models circulate air through a HEPA (High-Efficiency Particulate Air) filter, and often more than one. HEPA filters are certified to trap particulate matter as small as 0.3 microns, which covers dust, pollen and most bacteria. Some purifiers boast a medical-grade Hyper-HEPA filter that will go down to 0.003 microns — enough to pick smoke out of the air.

In conjunction with this, the more high-tech air purifiers can employ an extra line of defense. The Germ Guardian uses an optional UV light that renders many micro-organisms sterile, and an activated charcoal filter that can actually pull in and neutralize toxins through electrostatic attraction. There are also models that can ionize incoming particles, which are then sucked in by metal plates or other treated substances.

A word of caution on ozone, though. While they’re less common these days, some air purifiers generate ozone, which, according to the manufacturers, can deodorize and disinfect the air. The jury is still out on those claims, and in fact the presence of ozone in confined spaces can be more harmful than the pollutants you’re trying to get rid of.

For a measure of general effectiveness, you can look for a rating on most air purifiers called the CADR — Clean Air Delivery Rate. It’s a number that represents the cubic feet per minute (CFM) of air that has been cleared of all the particles of a given size. These ratings are recognized by the EPA and can be found on most devices. If you can’t find them, the number is fairly easy to calculate: Just take the CFM on the air purifier and multiply it by the percentage of a certain particle (smoke, pollen, etc.) that the machine can remove.

DWYM Fun Fact

That air purifier humming away in the corner of your room may look tranquil, but it was initially created for military use. The HEPA filters that are so common today were first employed to keep lab workers safe at the Manhattan Project, the 1940s scientific effort that led to the creation of the atomic bomb. Back then, scientists were less concerned with their ability to keep their allergies in check. They were using the filters to block out as much radioactive material as possible.

The Air Purifier Buying Guide

  • One of the first things you’ll want to consider when buying an air purifier is the kind of room you’ll be using it in. When it comes to price, this is usually the primary factor. A workhorse unit that can handle an entire living room and kitchen is going to run you significantly more than a machine that’s meant for a home office for good reason.
  • Are you looking for protection from allergies or just need to freshen up the air? A quick look at the specs for the purifier should tell you what particles it can effectively remove from the air. Again, a HEPA filter is going to do the trick for most common irritants and odors, including pet hair and dust. But if you live in a smoker’s house, look into something more robust.
  • Much like your air conditioner, you’ll likely be keeping an air purifier on for as long as you plan on breathing the air in that room. In a lot of cases, that might be all day, so power consumption matters. Frugal users might want to check out the wattage specs on prospective models. There are also features that can mitigate that electricity drain, such as timers. In most cases, your air purifier won’t be running all the time. It’ll cycle the air through a few times an hour, and you can adjust that number more or less with most models.
  • Another thing to figure into your price point are the filters. Like your AC, there’s upkeep involved. Check not only the price of your filter, but the frequency with which you’ll need to replace it.
  • Since they’re meant for indoor use, most air purifiers are better looking than, say, that wall AC unit you had in your dorm room at college. That said, few people want them as the focal point in a room. If you’re getting one for a small room, you likely want a small purifier — or at least one that’s nondescript. Sleekly designed at less than 17″ x 19″.
