#1 LEVOIT Air Purifier 

With their favorite quote: “One less snooze = a morning walk around the block”, the American brand Levoit is building up a very active community for air cleaning purposes. Their most favorite air purifier in the market – the Levoit LV-H132 comes with a 3-stage air filtration system:

  • Pre-filter – This fine preliminary filter is able to capture large particles of pollutants. This filter is only good for a very short time so it should be cleaned regularly.
  • True HEPA Filter – A True HEPA Filter can reduce 99.97% of down to 0.3 microns dust mites allergens, virus particles, pollen, bacteria particles.
  • Activated Carbon Filter – It is great at eliminating odors and smoke in your home.

There aren’t many True HEPA certified air purifiers in this price range. The LV-H132’s performance is 10% better than other HEPA filters and is therefore the best air purifier at a reasonable price. This purifier is perfect for anyone suffering from asthma or allergies. Its True HEPA filter meets the strictly standards to remove 99.9% of dust, smoke, odor, mold spores, pet dander and particles as small as 0.3 microns.

The Levoit LV-H132‘s design is small and elegant, with 2 main color editions: Black and White. This True HEPA purifier is small enough to be used in a bedroom or for personal use. The LVH132 has a room coverage of only 100 sq. ft.

This air purifier we believe is the best for your baby. You can give your children a peaceful and safe night’s sleep with the Nightlight function and Quiet mode of Levoit LVH132.

#2 IQAir – HealthPro Plus Air Purifier

This air purifier is used extensively in hospitals and other medical facilities. It was used to control the 2003 SARS outbreak in Hong Kong. The American Lung Association also selected IQ Air.

This air purifier is the most powerful of the units we have highlighted. It delivers more clean air per hour than any other comparable purifiers. But at a pretty steep price, the IQ air is quite pricey and requires the expensive pre-filter, odor, and Hyper-HEPA filter getting changed regularly. Moreover is not very energy-efficient, and those costs don’t normally cover an entire home.

The coverage area for the Healthpro plus is approximately 1,000 square feet, so it’s only suitable for a vast room or apartment use. Unless you live in an apartment or small house, it is not recommended. This IQ Air purifier can be a great choice if you are able to afford it. Those who are buying an air purifier for medical reasons are most likely to appreciate the Healthpro plus, despite its high price.

#3 RabbitAir MinusA2 Ultra Quiet HEPA Air Purifier

Rabbit Air is one leader in the U.S air purifier market, starting from 2004. Their Rabbit Air MinusA2 product is the latest to be competitive in the mid-range purifier market. Rabbit Air designed a new product to perfect this product. 6-stage purification & deodorization system to make the cleanest, freshest air possible in the world.

  1. Pre-filter – The polluted air must pass through a pre-filter, there it will capture all large particles, along with dust mites and some of pet hair.
  2. Medium Filter – Traps large pollen, pet dander, mold and dust particles that is small enough to bypass the Pre-filter.
  3. Advanced BioGS HEPA Filter – It is a True HEPA Filterthat captures 99.97% of all allergens, virus particles, pollen, mold and fungi particles down to 0.3 microns. Rabbit Air uses advanced technology to improve their HEPA Filter’s efficiency and life expectancy.
  4. Filter Customized – Double the protection with a variety of customized filters for specific needs like Germ Defense, Pet Allergy, Odor Remover, or Toxin Absorber.
  5. Activated Carbon Filter – Eliminates odors, smokes and chemical vapors.
  6. Ion Generator – The last line of defense is an ionizer to capture even the tiniest particles of pollutant and trap them into other filters. Can be switched off/on.

Another reason we love this air purifier will be its quiet operation. Rabbit Air has developed advanced technology to reduce noise levels. You will have a both quiet and powerful air purifier, all without a need for regular maintenance.

#4 Alen BreatheSmart 

The Alen breathe smart HEPA air purifier doesn’t filter the smallest particles in your home quite effectively as the IQ air because it uses a standard HEPA filter, additionally, it doesn’t have a separate odor filter.

It will not remove all common contaminants that can cause breathing and health problems. From an area up to 1,100 square feet at a lower price than the Healthpro plus. Its CADR rating, which measures how well it removes contaminants, is among the best on the market.

One excellent feature of the Alen model is its intuitive smart sensor, which can continuously sense the amount of pollution in the air and adjust the fan accordingly, you can also operate the unit in timed or manual modes to save energy, although this air purifier is Energy Star certified. It also has a night setting that lowers the fan speed and reduces the brightness of the LED indicators.

There’s also a filter monitor, one feature that you should know about is the breath Smart’s optional ionizing unit ,the latter remains a controversial subject, atoms that have been charged by the ionizer can more efficiently trap air particles, But ionized air can also cause breathing problems for those with sensitive or compromised lungs. The ionizer on the Alen can be easily turned off, though, if you prefer you can operate the unit without it.

This air purifier is highly effective and a good choice if you are concerned about your health and the quality and quantity of the air you breathe. it‘s equally attractive, with a high-tech look and 7 front color panels to choose from

#5 Germ Guardian AC4825

The 3-in-1 filtering unit prevents unpleasant odors, cleans the air and stops harmful bacteria and mould growth. To ensure the purifier functions optimally, the indicator light helps to indicate when to change the filter.

This air purifier has Slim profile – quiet on the first two settings – in third setting the noise of the fan is subtle – It has a UV light and is “True HEPA”. But if one could do it again, he/she would likely have spent more money and bought the Germguardian Ultra 4 in 1. The UV light is efficient and flashing. It is a long tube, as opposed to the Germguardian AC4825 that is a small bulb.

It also helps to prevent bacterial growth – A charcoal filter helps to effectively limit and thwart the growth of bacteria, microbes, and mold.

#6 Honeywell True HEPA Allergen Remover

Doctors consider Honeywell purifiers to be a vital part of a comprehensive allergy treatment program. The most efficient air purifiers keep 99.7% of tiny particles (0.3 microns or greater) that pass through their filters.

Honeywell HPA300 filters can capture dust, pollen grains and smoke from household activities. Some models have even passed a test to capture disease-causing germs in the air that passes through the filters.

Each Honeywell model is 99.97% efficient in capturing microscopic harmful particle, 0.3 microns and greater, from the air passing through it.
