There is almost an unlimited amount of things that can impact the quality of the air we breathe on a daily basis. Whether you’re looking at how deeply you breathe or the overall air quality, ensuring good breath hygiene is essential for anyone who wants to live better.
One of the easiest things to do to improve the air quality in your home is to invest in an air purifier to get rid of unwelcome particles and chemicals. While vacuuming regularly can help with this to some extent, getting a proper air purifier to quietly and invisibly remove dust and fine particles from the air does a much more thorough job. So let’s take a look at our best air purifiers for large rooms recommendations in today’s product review.
The Best Air Purifier For Large Rooms
For an all-around option that will ensure the finest, healthiest air you’ve ever breathed in your life, there is nothing better than Winix 5300-2 Air Purifier. Its true HEPA filter is one of the most impressive around, and this eliminates as much as 99.7% of airborne pollutants, allergens, dust, pet dander, mold spores, and just about anything else that will severely impact the air quality in your home. It does this through a high-tech three-stage cleaning system across five operational modes that include Turbo as well as Sleep to get the best performance on both ends of the spectrum.
Furthermore, the unique PlasmaWave system acts as a permanent filter. Through this, it breaks down odors, which is ideal for homes with pets, as well as chemical vapors that could cause respiratory issues in your home. If you are (or live with) someone with allergies, this is a crucial addition to any home to prevent illnesses and allergy flare-ups at the worst possible time.

A perfect choice for any home with pets, the Bissell Smart Purifier makes the home happier and healthier for them as well as you. Like any decent purifier, it comes with efficient three-stage filtration that captures 99.7% of 0.3 microns.

Besides this, the automate CirQulate system will adjust the settings to match the air quality in the home, and this makes sure it does not work too much (and equally, not enough), conserving energy and maintaining excellent performance, while also extending the filter’s lifespan.

Air Purifier For Large Rooms Buying Guide & FAQ
Features To Look For In Air Purifiers For Large Rooms
Once you know how powerful a machine you need and which type of air purifier might be best for your space, there are some extra features you might want to keep an eye open for when looking through our list of the top-rated air purifiers for large rooms. These include the following:
- Type of filter: Does your machine work with a Dust Pre-Filter, a HEPA filter, Electrostatic filtration, Active Carbon, etc.?
- How frequently will the filter need to be changed?
- How many times can the air purifier clean the air in my room in an hour?
- How noisy will the air purifier be when it's switched on?
- Does the air purifier have an auto mode?
- Do I need an air purifier that actively removes bad odors as well as improving air quality?
- There will, of course, be loads more things to consider when selecting your air purifier, but these questions should give you a good starting point to help you find the best air purifiers for your home.
Types Of Air Purifiers For Large Rooms
There are loads of different types of air purifiers for large rooms to choose from, coming in a range of sizes, different types of filters, and some with special added features making them particularly suitable for people with allergies or asthma, removing cigarette smells, or for pet owners. The two main types of air purifiers, however, are Filter Purifiers and Ionic Purifiers.
Filter Purifiers - Filter purifiers work by pulling air through a filter to trap any particles larger than air. The best options are True HEPA filters that remove over 99.9% of particles larger than 0.3 microns (this includes household dust particles, mold spores, pollen, and most tobacco smoke and other odor particles). HEPA stands for High-Efficiency Particle Arrestance.
Various membranes can be used in a Filter Purifier, with the most popular being activated charcoal, a layer that's particularly good for trapping allergens and odor particles.
Ionic Purifiers - Ionic purifiers work by taking advantage of electrostatic attraction, which refers to the attraction between two negatively charged ions. They actively seek out and destroy negatively charged ions from the air, which, luckily for us, are usually molecules, including dust, bacteria, and other unwelcome visitors. These types of purifiers can also be referred to as Electrostatic, Ionic Breeze, or Truman Cell Purifiers. Ionic Purifiers are often criticized as they run the risk of releasing harmful ozone particles while cleaning the air, so watch out for this!
