For a deeper exploration into filter types, read our article on a PCO air filter vs a HEPA filter.

Insider Tip

Pairing a plasma air purifier with a more extensive system can help you filter out far more airborne pollutants from your environment.

Explaining Plasma Air Purification

Plasma purifiers are a lesser-known but still a highly effective form of air cleaning technologies. The level of air cleaning they provide is on par with other add-on systems. They are also energy-efficient and budget-friendly for just about any household.

How do Plasma Air Purifiers work?

Plasma air purifiers specialize in capturing the small percentage of particles other purification systems might have missed, and this includes units with HEPA filters and allergen filters. They do this using both a positive and a negative electrical charge. The science is a bit more complicated than that, but you don’t necessarily need the specifics. We have a great article on PM2 5 vs HEPA filter options if you’re still curious about different filter types.

Are Plasma Air Purification Systems Effective?

While not as effective as a HEPA filter, plasma purification is still effective in its own right. The best part about them is that they’re budget-friendly and easy for anybody to invest in. They also have some of the top-rated air purifiers for allergies and dust.

Explaining HEPA Filter Air Purifiers

A HEPA air purifier is known for having excellent filtration efficiency. The HEPA filter is currently backed by federal agencies like the Department of Energy. This is because of its unbelievable ability to remove harmful pollutants from the air in your home. In our Honeywell HFD 120 Q review, we explore the benefits of using a HEPA air purifier and how this particular model stacks up against other options on the market.

How does a HEPA-Type Filter Work?

Although not too far removed, a HEPA filter differs from a traditional one. HEPA filters airborne particles through thick pleats to remove as many harmful particles as possible. Even larger particles like pet dander are kept well under control. But, as you’ll find in our Airthereal ADH80 review, HEPA filters are a crucial component to effective uses of air purifiers.

Is a HEPA Filter Air Purifier Effective?

A HEPA air purifier is one of the best defenses you have against airborne particles like pet dander. They improve air quality tremendously and kill unwanted organic compounds in the air. A wide variety of health benefits come with using a HEPA filter product. Read our Honeywell True HEPA air purifier review to start checking out HEPA-based units. Regardless of which filter you use, be sure to know how long to run an air purifier for optimal results.


Even low levels of ozone can be hazardous to human health, and you should avoid ozone generators at all costs.


What do I need to know about air purifiers and the COVID-19 pandemic?

The presence of adequate ventilation systems can significantly lower COVID-19 transmission. However, it is essential to note that those ventilation systems cannot prevent COVID-19 transmission altogether. Air purifiers have been crucial during the coronavirus pandemic.

Should I take precautions against the Covid-19 pandemic even in ventilated areas?

The COVID-19 pandemic is still very much ongoing, so you should take as many precautions as you can. Even if a public space seems to have excellent ventilation systems, remain six feet apart and wear a face covering.

How do ionic air purifiers work?

Ionic air purifiers work by emitting a negative charge. This is done by releasing ions into the air that flows through the purification system. This process might cause harmful ozone to be released, however. Ionic air purifiers might increase indoor air pollution by acting as ozone generators.

What should I consider about air purifiers before buying one?

Different types of air purifiers were made for different lifestyles and budgets. You’ll want to figure out what respiratory conditions you have that might influence your decision. Then, consider what environmental health risks you want to pinpoint. Filtration efficiency, air exchanges per hour, and energy consumption are all things to consider.

STAT: A recent study suggests that HEPA filters can lose a quarter of their efficiency in the space of 6 months. (source)
