Best air purifier Ozone free

Fresh, clean air. You need it, but the environment doesn't always provide it. If you've suffered long enough with sinus problems, allergies, or headaches due to pollutants in the air, it's time for an air purifier.

You can go up to three weeks without eating. You'll survive three to four days, on average, without fluids. But it only takes six minutes without air to damage your delicate brain, and survival beyond that is unlikely. The air you breathe is the most pressing life necessity, so why not take as many breaths as possible of pure, clean air?

Take a deep breath—if you can. Many of the things we do to keep energy costs down, such as fixing drafty doors and leaky windows, can also seal in pesky pollutants and irritants. Most people who buy air purifiers do so in hopes of easing asthma or allergies. But despite product claims, there's little definitive medical evidence that air purifiers help to relieve respiratory symptoms.

Here is the best air purifiers list you could count on in 2018.

The Pros and Cons of Best Air Purifiers

Pros:

They’re portable—most room air purifiers weigh from 10 to 20 pounds, have a handle, and stand on the floor or on a table, while heavier models might have wheels.

Many have a high-efficiency particulate air (HEPA) filter, which can capture ultrafine particles.

Keep in mind: Most HEPA filters need to be replaced annually, an expense that might approach the cost of the air cleaner, but a few models are now available with cleanable HEPA filters.

Cons:

Portable models that use either electrostatic-precipitator or ionizer technology could produce some ozone, a lung irritant.

Dedicated ozone generators, a subcategory of room models, produce large amounts of ozone by design. According to manufacturers, that is to reduce allergens such as dust, smoke, pollen, germs, and mold. Ozone, however, is a serious health concern, prompting the State of California to ban the sale of ozone generators (and other air purifiers that emit more than 50 parts per billion of ozone) from the general market.

Prices: Range from $50 to more than $1,000

Definitions for the best air purifiers

Here are the different types of filters air purifiers use:

  • HEPA filters (high-efficiency particulate arresting) are the most common, and the most effective. These super-filters remove 99% or more of airborne particles as small as 0.3 microns from the air. That includes most common allergens such as pet dander, mold spores, and pollen, along with many bacteria. HEPA filters don't combat VOCs and other gases, however, nor can they trap viruses, which are much smaller than 0.3 microns. HEPA filters can be pricey, however, and you'll need to replace the filter at least annually — more often if your home is especially dusty or smoky.
  • Activated carbon filters are best for capturing odors, smoke, VOCs, and other potentially harmful gases. They don't do a great job of removing dust and other allergens, though. Because of this, it's very common for an air purifier to have both types of filter. Activated carbon filters are much less expensive than HEPA filters, but generally, need more frequent replacement.
  • Electrostatic filters use an electric charge to attract large particles, some gases, dust, and most allergens. These types of air purifiers can be pricey, but you won't have to change the filter, just wipe it off periodically.
  • Ionizing air purifiers create a cloud of negatively charged atoms, which cause large particles to clump together. This makes it easier for the air purifier's filters to capture the pollutants. There is a concern, however, that some ionizers create excessive ozone, which is a known respiratory irritant. Typically, air purifiers have an ionizing function along with other types of filters.
