When choosing an air purifier, there are many factors to consider. With so many possibilities, choosing can take a lot of work.
Here are the best air purifiers to help you choose. Whether you’re looking for the best value, the most features, or the quietest operation, I’ve got you covered.
Choosing the best air purifier is hard because each allergy or asthma situation has different needs. This is a hard job made even harder because allergens and other types of home pollution are removed differently. Here are comparisons of various popular air purifiers.
Air purifiers with HEPA (High Energy Particle Arresting) filters were first made for the Atomic Energy Commission. They are used in commercial clean rooms to eliminate dust and other air pollution.
This is a paper or polymer sheet with tiny holes that let air flow through but not much else. Because the holes are so small, you need a lot of surface area for a reasonable airflow through the material.
Because of this, the medium is always folded in an accordion or zigzag pattern, so a small space has a lot of surface area. One company also uses a hybrid version of the technology, where the holes in the HEPA filter are slightly bigger to let more air through, but the air is charged with electrostatic wands. Which then attracts any smaller particles that get through the holes. HEPA Filters work well in the home to catch particles. The disadvantage is that the filters must be changed often (every 6 months to 5 years, depending on the manufacturer).
Before buying, you should also look at how much air gets past the filter, how loud the fan is, how long the filter lasts, and the price of both the original unit and replacement filters.
The review of any HEPA unit depends on how well it works (how much air gets past the filter), how loud the fan is, how long the filter lasts, and how much it costs.
UV air purifiers employ ultraviolet light. When ultraviolet light is strong enough, it can destroy the DNA of microorganisms such as bacteria and viruses.
The problem with a UV air purifier is that it only removes a few gas pollutants and no air particles. Then you would need to buy a UV air purifier with another type or one that combines with another filter system.
Air purifiers are small machines that clean the air by putting out a stream of negatively charged ions. These ions put an electronic charge on pollution particles, so when the particles bump into something, they stick because of the electronic charge.
These are used on US submarines and poultry industry to keep feather dust down. They do what they say they do, but they have some very obvious problems.
Particles end up on your walls, so the walls turn black near the device.
Second, since they usually don’t have a fan, they only work in a limited area. They also do nothing to stop gas pollution; some may put out dangerous ozone.
You can see from the three examples above that there are different types of air purifiers.
Your needs will dictate the best air purifier. If you suffer from allergies, you’ll want to choose a purifier designed to remove allergens from the air. If you have asthma, you’ll want to choose a purifier that can remove particles and chemicals from the air.
And if you’re concerned about energy efficiency, you’ll want to choose a purifier that doesn’t use too much electricity.
Find the right purifier for your needs by doing research and shopping around. Refrain from letting advertising hype sway your decision. Getting the wrong air purifier is just as bad as not having one.
