Best Air Purifier for 1000 sq. ft. Large Room Reviews

If you want a good-looking purifier that covers 1,000 square feet of space, this Bissel model may be perfect for you. It looks like a vintage radio set with its front-mounted mesh pre-filter which captures airborne debris. The short faux wood legs which lift the device off the ground also add to its antique aesthetic. The dial on top operates the digital display and controls fan speed and switches between modes. 

There is an activated carbon filter inside as well as a HEPA filter that captures particles down to 0.3 microns, and takes care of any gases, VOCs, pollen, dust, smoke, pet hair and dander, as well as cooking, smoke, and other household odors. 

With its Automated CirQulate System, the air is monitored and readings are provided to share with you the real-time air quality of your home. It will also adjust the fan speed so that it is not running stronger than needed, in order to cleanse your home, saving you on electricity.

For night time use, there is a whisper-quiet fan option and an automated Night mode, which clean the air without interrupting your sleep. Rated to quickly cleanse the air in rooms up to 308 sq. ft., this is a great machine to use in bedrooms, basements, offices, and living rooms. 

Pros:

  • Lends a classic look to any room
  • The filters are easy to change
  • The fan is large and works well for circulating air in bigger spaces

Cons:

  • Limited options, does not have a remote
  • No handle makes it more difficult to move around the home

As with anyone who struggles with seasonal allergies, finding relief often isn’t easy. The first thing you notice when taking it out of the box is its strong build quality. Not made from cheap materials, there is a peace of mind that comes from a sturdy air purifier. Easy to set up and get running, we started it off on high to quickly clean the air. Yes, it was a bit loud, but it was also sucking in and expelling a lot of air. After we let it run on high for an hour we reduced the fan speed to low as a maintenance speed and at that level, we were quick to stop noticing the sound at all. With a few hours this relieved our allergy symptoms and noticeable improved the quality of the air in our house. 

This air purifier is a beast! Medical-grade filters work tirelessly to remove air impurities down to .0003 microns, creating some of the purest air possible. 

Using a very powerful fan that takes in and circulates 780 cubic feet of air per minute, you can clean a whole room in no time! The craftsmanship and construction is solidly built, and there are 6 fan speeds that feed air though the medical-grade true HEPA filter before pushing it back into the room in a 320 degree arc.

This is the kind of air purifier your doctor will recommend to you. The award-winning IQAir HealthPro Plus air purifier has an incredibly efficient proprietary HEPA filter that is more effective than standard true HEPA filters. This removes pet dander, smoke and even airborne viruses. 

As this is a medical-grade air purifier, it’s best suited for people with severe allergies, compromised immune systems, or who want an absolutely pure air environment. With its powerful filtration system, it can clean the air of a room up to 1125 sq. ft., making it great air purifier for the entire house. 

The IQAir has an intuitive and easy-to-use remote, multiple programmable options, filter-life monitoring, and color-coded lights to indicate when it’s time to change the filter.

The display lighting darkens completely, which manes you can keep this running overnight without any interruptions.

  • Comes in a wide variety of designer colors
  • Suitable for 1,000+ square foot rooms
  • Features a turbo speed mode for quickly purifying air in large rooms
  • Very quiet on low fan speed

Trial Results

We placed the BreatheSmart air purifier in our living room during wildfire season, when our house seemed to always be filled with a thin haze. It was really affecting our breathing, giving us throat irritation and itchy eyes, and doing these filter tests during this time was a good way to gauge their usefulness. 
We started off on high in order to quickly clean the air in our 600 sq. ft. space, and after an hour reduced the fan speed to low. On the lowest setting it was very quiet and within an hour we noticed a big difference in the clarity of the air. By that evening we no longer had the physical symptoms we were suffering with and we turned on Auto-Mode and let the device work it’s magic.
