Best Brand Choice Without Exception

I have used this model Levoit Air Purifier with True-HEPA Filter with excellent results for my stuffy summertime allergen sensitive nose and sinuses. With the 3 different filters, everything is blocked out. I move it to my bedroom at night, turn off its lights, and it’s so quiet I sleep soundly without stuffiness or sneezing now. The easy to use unit is highly endorsed for its effectiveness and all the praises I can give it.

Best Brand Choice Without Exception

The Pure Enrichment PureZone is the most exciting air purifier I’ve ever owned! I’ve had many, especially when the kids were little. I use this one for my sinus congestion and am thinking of getting another one for the musty smell in the laundry room. What was a selling feature for me is the one only filter that holds the 3 filters as one item. It is easier to change than the 3 individual ones. My first HEPA filter in this air purifier lasted about 6 months. I am so thrilled with this model and know you will be fond of it as much as I am.

What is an Air Purifier?

To rid your home of contamination and pollutants, the small electrical piece of equipment, known as an air purifier will improve your air quality in a matter of only a few days. The air will be cleaner, not feel as heavy, dust will be gone, and everyone will breathe better.

If you want a small humidifier, try using a diffuser with essential oils or without oils to be a small humidifier with only water added. It will cover a small local area and provide benefits.

Who can use an Air Purifier?

Anyone who wants clean air can use an air purifier. Air purifiers have no side effects and all people want healthy air to breathe in. No one wants to dust furniture constantly for pet hairs and dander and vacuum the carpet everyday.

Where can I use an Air Purifier?

Put a portable air purifier in any room of your house. You might want it in the room where you spend the most time, or purchase several for constant purification in other rooms. You might spend a lot of time in the lower level or basement of your home and an air purifier would be beneficial there as well if the basement has mold spores and a musky smell. Always place them two feet from walls and doors to permit airflow.

Types of Air Purifiers

Filters Air Purifiers

Grill-style air cleaners use filters. Material can be fiberglass, cotton, foam, or synthetic fibers. The material compactness control the particle size passing through it. Thick dense filter material grab super small particulates in the air. Pleated filters have an increased surface are to grab the particles. Some filters can be washed and some must be replaced.

HEPA (High Efficiency Particulate Air) filters remove particles to comply with the US Department of Energy (DOE) regulations. Any material can be used for the filter but is must meet the standard of 0.03% for particles 0.3 micrometers in size and larger. Airflow is specific for penetrating the filter. HEPA filters are used in high-end vacuums and other devices using filters for home use or industrial use.

Activated Charcoal Filters are used as an adsorption (not absorption) material for capturing fumes, odors, and chemicals in your air. A familiar adsorbent is activated charcoal that is porous with tiny areas to catch molecules passing into it. Large particles stick to the numerous pores in the charcoal.

HEPA (High Efficiency Particulate Air)

Ionizing Air Purifiers

The air purifiers use a corona discharge for producing ions that are negatively charged molecules. Dust and other large particles are easier to be ionized since they are larger to be passed through the corona discharge. Two metal plates in the air purifier are charged with one being negative and one positive that attract the particles that are drawn to each other when they have opposite charges where they cluster with each other and become heavier to settle from the air.

UV Light Air Purifiers

Ultraviolet (UV) light causes specific microorganisms to be harmless and non-reproductive. Airborne viruses, bacteria, and mold spores pass through the UV light that cleans the air as the pathogens pass through killing them.

Ozone Generating Air Purifiers

Similar to an ionizer, the ozone generator alters oxygen molecules and turns them into ozone. These molecules have three oxygen atoms. In nature, the atmosphere is dioxygen that is made of two oxygen atoms. Exposed to UV light or a corona discharge, some of the molecules split into free oxygen atoms. Some of the atoms make ozone yet most of the oxygen combines again into dioxygen.

As for ozone, it is a toxic gas, that is not a stable molecule, can react with other chemicals in the air making new compounds that can be more unsafe than the ozone. Manufacturers of ozone devices state that ozone disinfects the air, provides health benefits, and deodorizes the air. There are compelling indications that this is not true. Ozone causes corrosion and rusts metal.

Important Features to Consider When Choosing an Air Purifier

1. Clean Air Delivery Rate (CADR)

Clean Air Delivery Rate (CADR) is the amount of filtered air volume returned to the air after being filtered by the air purifier. Three measurements are specified for dust, tobacco smoke, and pollen. The greater the CADR number the higher the air purifier is filtering your inside air.

Many different brands of air purifiers will have this seal. The acronym means Association of Home Appliance Manufacturers with the certified Clean Air Delivery Rate (CADR) logo. The testing certification is used for rating air purifiers by the Consumer Union for its publication of Consumer Reports. This test and certification is recognized by the American National Standards Institute, ANSI.

What is the Clean Air Delivery Rate?

CADR was established in the early 1980s and AHAM in 1967. CADR shows the rate of pollutants and contaminates reduced in a testing chamber. This test determines the air purifier’s capability for removing certain particulates in a controlled chamber and it is measured for its ability to remove 0.10 to 11 microns from the air for pollen, dust, and smoke.

Results Information

Size of the particle eliminated
Percentage of particles eliminated
Actual air volume moving through the unit

Three Groups of Sizes for Particles Tested

Pollen: 5.0 – 11.0 microns
Cigarette Smoke: 0.10 – 1.0 microns
Fine Dust: 0.5 – 3.0 microns

Particle percentages are converted to numerical rates ranging from 0 – 400 for smoke and 0 – 450 for pollen and dust.

Interpretation for Air Purifier Efficiency

The test results tell you comparison numbers to determine the performance of air purifiers. It gives an overall performance of the filtering system as well do help you determine how large of a unit you will need for your situation.

2. Area Coverage

It is difficult to purify air in large areas if you purchase an air purifier that is too small. When you buy a unit that is too small, the air purification will not be done well. You will be wasting your money.

To determine the square footage of the area, multiply the length by the width of the room. A room that is 12- by 14-feet = 168-square feet. Purchase a unit that is not more than 67% of the room size you want the air purifier to clean. If your room is 168-square feet, 67% of that is 113-square feet. You will have more air changes per hour (ACH) from your unit so do the math. Do not purchase a unit that only delivers 2 air changes each hour. Allergy sufferers like to have 5 or more air changes each hour.

There is no one air purifier that is better than another. You will need to identify the type you want, the features, and whether it has a remote control, and if it works for your square footage for the area you want to cover.

3. Noise Level Compared to Other Sounds

Most manufacturers of air purifiers indicate the decibel (dB) level for each fan speed. This comparison might help you understand the dB rating better for air purifiers.

Decibel (dB) Comparisons
00-dB Hearing Lowest Level
10-dB Normal Breathing Sounds
20-dB Falling/Rustling Leaves
30-dB The Average Whisper
40-dB Light Rainfall
50-dB Heavy Rainfall
60-dB Box Fan on High
60-65 dB Normal Talking @ 100 ft.
70-dB Vacuum Cleaner
90-95 dB Hearing Loss
90-dB Train Whistle @ 500 ft.
98-dB Electric Hand Drill
115-dB Loud Rock Music
140-dB Jet Engine @ 100 ft.
165-dB Blast from 12-Gauge Shotgun
180-dB Hearing Death
194-dB Loudest Possible Sound

Each person perceives sound differently. Sound levels can be affected by “traps” such as drapes and carpet and be quieter. Sound will reflect when there are no soft surfaces to absorb the sound vibration. Your distance from the unit will change the sound; the speed will change the decibels. The faster (higher) it runs the louder it will be since it is running faster to push more air. The lower the fan, the lower the noise level.

4. Filter Reset

Check your manufacturer’s manual for the filter reset button location how to use it.

5. Airflow Rate (CFM)

5. Airflow Rate (CFM)

Airflow rate is a huge consideration when purchasing an air purifier. Airflow is measured in CFM (cubic feet per minute). Air is a gas and it can be calculated by its mass or volume. The air cleaner manufacturers describe airflow in volume. Airflow is contingent on two aspects: the built-in fan and the filter’s efficiency.

6. Air Changes per Hour (ACH)

6. Air Changes per Hour (ACH)

Air Changes per Hour (ACH) lets you know the number of times the air is replaced in an hour. The higher the number the better it is. The number can fluctuate between 1 and 7. The higher the number the more the efficiency. If your home has contaminants, it is best that the unit is capable of handling 2 or more air changes each hour.

Be sure when researching different models for how many air changes the unit performs each hour. Some of the air purifiers are less expensive and are most efficient when the fan is running full power and that causes noise. With more high-end models, the number of air changes will be more with lower fan settings.

7. Service Indicator Light

7. Service Indicator Light

There is no actual service to be done for an air purifier. A long-life LED or LCD indicator light will illuminate when it is time to change the filters. Some air purifier models will provide electronic readouts with built-in timers to indicate the length of time filters will last.

8. Dust Sensor and Air-Quality Monitor

8. Dust Sensor and Air-Quality Monitor

Dust sensors detect particle concentration in the air by using optical sensing devices. The dust sensor detects very small particles such as cigarette smoke from larger particles such as dust.

Air quality monitors use technology and engineering that allows monitoring of indoor air quality with an LCD screen that provides small and large particle counts with a dynamic bar graph showing actual count readings

9. Asthma and Allergy Friendly

For the 60+ millions of Americans afflicted with asthma, allergies, COPD, and other respiratory issues, you will find that air purifiers today are made with efficient filters, the best one being True-HEPA, for removing pollutants in your home or where you spend most of your time. We say air purifiers are “friendly” because they respond to your problems.

Tips for all Air Purifiers

Locate your air purifier near the outlet and avoid using an extension cord. If you must use an extension cord, make sure it is rated for an appliance with the correct AWG.

Some air purifiers are polarized at the plug meaning it has a blade wider than the other. It fits only one way to avoid shock. Some units have a 2-prong plug and some have 3-prong grounded plug with a rounded end next to the two blades. Do not use an adapter to plug it in. It will not be grounded and a fire could start.

Countries outside of the USA need a 220/240-Volt adapter. Know that 220 is 110-Volts twice—the power used for clothes dryers and electric stoves. If anyone plugs a 110-Volt plug into a 220-Volt outlet, the unit will spark and die. It cannot be fixed.

Refrain from putting heavy things on the air purifier and do not sit or stand on it.

Always turn the air purifier off and disconnect it from the wall outlet when changing filters or cleaning it.

Air purifiers should be placed at least 2-feet from walls, doors, and furniture. Check your User’s Manual because some units need 3-feet of clearance.
