Though coming with a minimalist design to place on your desk, the Levoit Compact Air Purifier is powerful enough to capture up to 99.7% of odor, smoke, pollen, dust, pet dander, and mold spores.

That’s why it is the best HEPA air purifier in terms of a great entry-level model!

Instead of cleaning the air by irons or UVs, the device boasts a three-stage filtration system for optimal purifying performance.

It consists of a fine preliminary filter, a verified True HEPA filter, and an activated carbon filter guaranteeing to filter PM 2.5 air pollution as allergens as small as 0.3 microns and larger.

As a plus, 5 basic function buttons and three fan settings (high, medium, and low) allow you to adjust the speed and your purifier’s volume for multiple conditions.

It means that wherever you put your device, you can always enjoy fresh and clean air.

But for the lack of auto shut-off system and light notification for filter replacement, the LEVOIT LV-H132 Air Purifier could receive many more positive comments.

However, if you are looking for an affordable purifier or a compact unit that you can use while traveling, this product by LEVOIT is worth considering.

NOTE: Ensure a 15” clear area around all sides of your air purifier for the best purifying performance.

Are you looking for a compact yet powerful air purifier that helps remove harmful allergens and germ and make the indoor air cleaner? Then, the Hamilton Beach Air Purifier is well worth your try!

Like other excellent HEPA air purifier, the Hamilton Beach Air Purifier also possess performance-oriented HEPA filters which can filter out 99% of viruses and airborne particles as small as 0.3 microns.

However, what makes it outstanding is the permanent pre-filter and HEPA-grade filter that can be easily vacuumed clean.

Besides capturing even the tiniest particles, these two filters also work in conjunction to remove light odors released by cooking, pets, or chemical gases better than the HEPA-grade filter itself.

Also, they help you save much money purchasing replacement filters.

This key purifying technology is perfect for heavy-duty air sanitizing in rooms as large as 160 square feet.

The Hamilton Beach Air Purifier has a ton of great features, but it also has a fair share of pros and cons.

Some pet owners are not satisfied with this unit’s pet hair-capturing ability. And when operating on the higher speed option, it can produce loud and noisy sound.


  • ​Equipped with a Permanent HEPA Filter Black
  • ​Free of worry about the sound of a chugging train while the purifier is running
  • ​Easy to move around
  • ​Affordable model on our list
  • ​Simple to operate
  • ​3 ultra-quiet speed settings suitable for use all day long
  • ​Perfect for medium and large rooms


  • ​Not good at removing pet hair

If you are incredibly sensitive to noise, then the Pure Enrichment PureZone 3-in-1 True HEPA Air Purifier is your best bet.

With the maximum noise level of merely 30dB, this unit by Pure Enrichment silently sanitizes the air and reduces unpleasant odors inside your bedrooms for more comfortable breathing.

That means that even the lightest sleepers can have a restful sleep while having this device run through the night. However, this purifier has more to offer than just a silent operator.

When it comes to the innovative 3-in-1 functionality, we don’t see much of a difference between this model and the Levoit Compact Air Purifier other than the Filter Reset Indicator telling you when to clean the filters.

What we also like about this average all-around performer is its optional automatic off timer, which will turn the unit off after two, four, or eight hours of continuous operation.

That way, not only does it promote energy efficiency, but it also saves you from remembering to shut your purifier off before heading to work.

Even though the Pure Enrichment PureZone 3-in-1 True HEPA Air Purifier can work pretty well in a small living area, it seems to struggle a little bit in rooms larger than 100 square feet.


  • ​Equipped with a whisper-quiet operation and 3-in-1 HEPA filter
  • ​Automatic off timer
  • ​Able to remove up to 99.97% of smoke, pollen, dust, mold spores, pet dander, and household odors
  • ​Easy to operate and maintain
  • ​Energy-saving and cost-effective


  • ​The unpleasant plastic smell on the very first use
  • ​Not suitable for rooms larger than 100 square feet
