How Air Purifiers Work
In general, air purifiers use fine sieves called air filters to trap and remove contaminants from the air. As such, air purifies with finer sieves are generally more efficient because they are able to trap smaller pollutant particles. Examples of indoor air pollutants include pathogens, bacteria, viruses, antigens, bad odors, toxins, irritants, and VOCs. With this in mind, the US Department of Energy (DOE) has set air purification benchmarks that manufacturers of air purifiers must meet.
For instance, air purifiers based on HEPA technology must remove at least 99.97% of air pollutants larger than 0.3 microns. A micron is a unit utilized to measure the size of air particles and it is equivalent to 1/25,400 of an inch. Other common air purifying technologies include Thermodynamic Sterilization (TSS) and Ultraviolet Germicidal Irradiation (UVGI).
What to look when choosing Best Air Purifier
Some of the fundamental factors to consider when shopping for an air purifier include:
There are primarily two types of air purifiers: room air purifies and whole-house air purifiers. The former is typically smaller and less expensive compared to the latter. According to Consumer Reports, a room purifier is a right choice if your home does not have a forced-air heating/cooling system or if you are shopping for an air purifier that you can move from room to room.
On the other hand, a full-house air purifier is an ideal choice if your home has a forced-air heating system. At this point of view, it is worth mentioning a sub-category of room air purifiers called dedicated ozone generators that are designed to emit an appreciable amount of ozone.
However, the US Environmental Protection Agency (EPA) warns consumers to avoid such air purifiers because ozone can damage the lungs and worsen chronic respiratory diseases such as asthma when inhaled. Healthy people can also experience breathing problems after inhaling ozone.
Also, a research published in the New England Journal of Medicine found that exposure to even low levels of ozone increases the risk of developing severe health conditions including pneumonia and chronic obstructive pulmonary disease.
Commercially available air purifiers vary widely depending on the type of air filtration technology deployed. Presently, HEPA technology is probably the most widely used technology in air purifiers. This technology was basically developed by the US Atomic Energy Commission to remove radioactive dust particles from the air.
HEPA filters are manufactured from finely woven glass particles that form a pleated surface area for trapping air pollutants larger than 0.3 microns. Although HEPA filters are highly effective, they are expensive because they require replacing after 12 to 18 months depending on usage.
The cost of a single HEPA filter ranges from $70 to $125. Moreover, the dense structure of HEPA filters means they are not as energy-efficient as other types of filters.
Besides HEPA technology, some air purifiers use Ultra Low Penetrating Air (ULPA) technology. Simply put, ULPA is a stricter version of HEPA air filtration technology that was developed for use in hospitals and “clean rooms” such as those found in the semiconductor manufacturing sector.
Another category of air purifiers uses activated carbon filters to remove air pollutants found in indoor environments. To achieve this goal, they rely on carbon treated with oxygen thereby opening millions of tiny pores that are ideal for absorbing/bonding with pollutant particles. Air purifiers that use charged media filters, in essence, rely on two technologies: an electrostatic charge generator and a particle filter.
Unlike air purifiers with HEPA filters, those with charged media filters can trap particles as small as 0.1 microns. The downside is accused media filters lose their efficiency quickly. Some manufacturers produce air purifiers that use antibacterial and germicidal filters, which are simply HEPA filters treated with chemical compounds that can kill harmful microorganisms such as bacteria.
Photocatalytic oxidation (PCO) is another type of air filtration technology that is based on a metal plate coated with titanium dioxide and uses UV light to break the chemical bonds that hold pollutant molecules together. Other types of conventional air filtration technologies include electrostatic precipitator, ion generator, photo plasma, polarized media electronic and titanium dioxide air filtration technology.
The size of an air purifier is calculated using the Clean Air Delivery Rate (CADR) metric, which was produced by the Association of Home Appliance Manufacturers (AHAM). In essence, CADR is a metric based on a number of cubic feet of air an air purifier can filter per minute. As such, a high CADR figure means a more efficient air purifier and vice versa. To calculate the CADR for a room, multiply its square footage by 0.75.
The features of an air purifier typically vary depending on the product size, model, and brand. Still, one of the most common and useful features is a fan for sucking in air. An article published by Consumer Reports states that air purifiers without fans tend to work poorly compared to purifiers with fans.
Another useful feature is a servicing indicator to alert you when it is time to replace essential parts such as the air filter. Other key features found in air purifiers include a dust sensor, UV-C sanitizer, filtering frequency controller, and air quality monitor. Fortunately, consumers can use product comparison sites to evaluate and compare air purifier features. This is in addition to comparing the prices of different air purifiers.

2. Honeywell HPA300 Air Purifier – True HEPA Allergen Remover
Honeywell air purifiers are considered by doctors as a crucial part of a total allergy treatment program. The most efficient air purifiers retain 99.7% of the tiny particles (0.3 microns and greater) that go through their filters.
Honeywell HPA300 air filters are capable of keeping airborne particles such as dust, pollen grains, smoke emanating from household activities, pet dander and mold spores. Certain models have passed a test to trap disease-causing germs from the air passing through the air filters.
These air filtering products utilize a mechanical filtration process — which means that a fan sucks in particle-laden air into the compact unit and makes the air pass through a Honeywell HPA300 filter, cleaning and recirculating the air in a room multiple times an hour.
And, Honeywell True HEPA air purifiers do not recirculate ozone back into the air after the filtration process is complete, making them the perfect air purifier for patients suffering from breathing difficulties.
- A silent fan sucks room air into the compact unit, circulating and cleaning the air multiple times an hour.
- The air then goes through a stench absorbing pre-filter to lessen unwanted odors and trap big particles like dust, pet dander or lint.
- The air passes through highly efficient True HEPA filters that capture up to 99.97% of particles, 0.3 microns or larger, from the air that passes through the filters.
- Clean, fresh quality air is recirculated back into the room.
Every Honeywell model is about 99.97% effective in capturing microscopic harmful particles, 0.3 microns or greater, from the air that goes through the filters.
Easy tap electronic controls with about three levels of air cleaning added with Turbo Clean setting & 2, 4, & 8-hour timer. Electronic filter replacement reminders are a bonus.

Some of the essential considerations when shopping for an air purifier include the air filtration technology, size, type, and features. Most of the air purifiers in the recent market today use High-Efficiency Particulate Air (HEPA), Ultra Low Penetrating Air (ULPA), activated carbon filter, charged media filter, antibacterial and germicidal filter, photocatalytic oxidation, ion generator, ozone generator, electrostatic precipitator and titanium dioxide air filtration technology. However, you should avoid air filters that use ozone generator filters because they tend to increase the risk of developing respiratory diseases.
