Air purifier reviews: what you need to know


Are you in need of an air purifier for pollen, allergen, smoke, gas or dander? Determine the contaminant you want the air purifier to remove and which meet your health worries. This will assist you in selecting the right system since manufacturers make certain air filters to remove certain contaminants. So read our review and you will know what you need).

The filter efficiency

You can use the particle size that the air purifier captures to measure its efficiency. For example, sizes below 0.3 microns are a better capture sizes for air purifiers. Mold, pollen, dust mites, pet dander and bacteria are usually within the range of 0.5 and 0.3 microns and the best air purifiers can trap the contaminants or things with a size above 0.3 microns.

Air filters with a size of 0.3 microns cannot filter air contaminants like chemical fumes, viruses and cigarette smoke. And if your aim is to remove such contaminants, you should purchase an activated carbon filter, an ultraviolent air cleaner or an ionizer.

Clean air delivery rate

Clean Air Delivery Rate (CADR) is a standardized measurement for the total air volume an air purification system will clean of a particular pollutant within an hour. More efficient units will have a higher number. Another measurement you should possibly consider is Cubic Feet per Minute (CFM). The unit of measurement represents the amount of air that flows through the unit within a minute. Considering the measurement is important because you won’t get the air purifier’s full value if the air purifier unit filters a very small amount of air in a minute. A 350-400 CPM is a very powerful air cleaner.

The noise level

Comprehensive air purifier reviews will help you if you need purifier that will run for 24 hours in a day, the noise consideration is very important since it can become an issue. Manufacturers of air purifiers will list each purifier’s fan speed decibel rating. The following shows the sound air purifiers make depending on the decibel measurement.


  • 10dB: breathing
  • 20Db: falling leaves
  • 30dB: whispers
  • 40dB: raindrops
  • 50dB: average room
  • 60dB: normal conversation
  • 70dB: vacuum cleaner

Reliability and warranty

Any time you purchase a cheaper air purifier with shorter warranty, most likely, you will find yourself replacing the unit after a very short time than you would want. To get the best air purifier, you should choose a properly established manufacturer and who offers a comprehensive warranty. A better warranty is one offering 5 years on the motor parts and the main fan. Reliable purifiers’ components shouldn’t have any problems provided you are replacing or cleaning its filters periodically.

Furthermore, an efficient air purifier forms a great investment and you should not take it lightly as it will affect the health of your family. Study the market to identify the available technologies and buy from the reputable manufacturers or retailers who will be willing to work with you to determine the system that perfectly fits your needs and which offers a longer time warranty.


Common types of air purifiers

Air purifiers are in many varieties. For example, there are portable air purifiers made to clean specific sized rooms and whole house installed air purifiers which work with HVAC systems inside the home. As we reviewed, portable room air purifiers are the least expensive and are also cost effective in air purification.

You should choose a portable air purifier for your home depending on its cleaning technology. There are HEPA filtration, negative ion generation and electrostatic purification models. Moreover, there are air purifiers that use a combination of the techniques and there are others made specifically for chemical removal. Some air purifiers feature other technologies like ultraviolent technology which removes bacteria, viruses, odors, gaseous chemicals, volatile organic compounds and fungi. Activated carbon blends and some other substances may assist in capturing odors and gases.

What is HEPA filter?

High Efficiency Particulate Air (HEPA) filters are proven filtration devices which most manufacturers continue to improve. HEPA filters are able to capture 99.9% of particles over 0.3 microns.

Even though studies highly vary depending on their source, researchers have proved that indoor air gets more polluted than outdoor air. Therefore, you should consider purchasing an air purifier to maintain the health of your family. Thank you for reding our reviews, guys!


  1. Since this year’s sensitivity period is predicted to be previous and much more severe as a result of very early summer, I have already started observing that throughout the day my eyes become itchy and my neck scratchy, both symptoms happen reduced or entirely gone once I run the Honeywell True HEPA air purifier

    what model do you actually suggest to buy?
