When you want to make the air in your home cleaner, you can opt for an air ionizer or air purifier. An air ionizer is a type of air purifier. Still, in this article, the term “air purifier” refers to HEPA air purifiers and the term “air ionizer” refers to ionic air purifiers.

Air ionizers use negatively charged ions that transfer their charges to air pollutant particles in the environment, causing them to stick together and eventually fall to the floor. They can then be vacuumed up. Air purifiers use a fan to suck air into the room into them and physical filtration to trap pollutant particles.

An air ionizer is a type of air purifier that removes pollutant particles — such as dust, pollen and pet dander — from the air by releasing negatively charged ions. These ions impart their negative charge to airborne particles, causing them to stick together. 

Once enough pollutant particles have stuck together, they become too heavy to remain in the air and fall to the floor, where they’ll be picked up the next time you vacuum. Some models feature oppositely charged plates to attract these particles when they pass through the ionizer air purifier.

Ionizers tend to be cheaper than HEPA air purifiers covering similar square footage, which is a plus if you’re on a tight budget.

This multipurpose air ionizer uses ionic technology to purify the air and features a HEPA filter to mechanically filter out and trap tiny particles that a standard ionizer might miss. It also has a carbon filter, which helps it remove odors from the air, such as those caused by pets or smoke. It’s great for large areas of up to 3,700 square feet.

Envion Ionic Pro 500 Square Foot Ionic Air Purifier

This nifty ionizer air purifier can clean the whole air volume in a medium or a large room of up to 500 square feet as many as three times in an hour. It combines HEPA filtration with ionic technology to cover all the bases.

Although it also contains a HEPA filter, this purifier uses ionic technology to tackle fine particles. As an ionizer air purifier, it’s great for large spaces of up to 1,500 square feet. It has a real-time air quality monitor to keep you apprised of the condition of air in your home.

Clarifion Air Ionizers for Home

You get three ionizer air purifiers in this pack. Each Clarifion air ionizer is extremely compact and easy to install and use. Just plug your Clarifon air ionizer into an outlet and it takes up a similar amount of space as a plug-in air freshener. The Clarifon air ionizer is whisper-quiet and doesn’t take up any floor space or counter space. 

Holmes True HEPA Allergen Remover Mini Tower Air Purifier with Optional Ionizer

Combining HEPA filtration with air ionizing technology, you get the benefits of both types of air purifiers. It’s ideal for relatively compact spaces of up to 80 square feet. It’s a great air purifier under $100.

A. Ionizers remove particles, microbes and odors from the air. This makes the air healthier to breathe and feel fresher. They’re of particular benefit to people who suffer from allergies and asthma, since they remove allergens from the air, as well as particles that can exacerbate asthma. Ionizers that release ozone can also kill or prevent the growth of viruses, meaning you may get sick less often. 

A. Yes, ionizers work, but you should know what to expect as they may not do everything you expect them to do. While they remove particles from the air, they don’t entirely get rid of them — these particles stick together until they get heavy enough to fall to the floor. So you’ll only truly remove them from the room when you vacuum and clean surfaces like tables and counters. 

Air purifiers use HEPA filtration systems to remove and trap airborne particles. HEPA filters can trap at least 99.97% of all particles down to the size of 0.3 microns. 

This includes mold spores, pollen, dust, bacteria and viruses. HEPA air purifiers are ideal for anyone who suffers from environmental allergies, such as hay fever or dust allergies. You can find some basic air purifiers for around $50, but you’ll pay at least $100-$200 for a quality model. Top-end HEPA air purifiers can cost more than $1,000.

Levoit Air Purifier for Small Space

As a true HEPA model, this Levoit air purifier doesn’t emit ozone and can trap particles such as pollen, pet dander and mold spores. It runs quietly and is perfect for rooms of up to 300 square feet.

A. Air purifiers are good for trapping and eliminating particles from the air, including pollen, pet dander and dust. They trap the particles in their filters, where you can wash them down the sink by cleaning the filter. They’re good for improving air quality and limiting the allergens in the air, which can help people with allergies and respiratory issues. 

A. Whether you want to sleep with an air purifier on is up to you, but it’s safe to do so. It may also improve your nighttime breathing, helping you to sleep better. 

Objectively, HEPA air purifiers do a better job of cleaning the air and trapping pollutant particles than ionic air purifiers. They don’t emit ozone and they don’t cause particles to drop and remain in your home until you clean them up. Therefore, an air purifier is usually the better choice over an air ionizer, especially if you have allergies. 

However, you might consider an air ionizer if you need to clean the air in a large space on a low budget. Air ionizers are also great if you don’t like the idea of cleaning filters or having an ongoing cost to replace them. Some are also great for small spaces due to their compact size, such as the Clarifon air ionizer. 

It’s up to you which to buy, but for most people, a HEPA air purifier makes the most sense. This is particularly true if you opt for a trusted brand, such as a Levoit air purifier or a Dyson air purifier.
