Best Air Purifier Buying Guide & FAQ
These 15 air purifiers are the best of the bunch, and we’re confident you’ll find the perfect option for your home somewhere on the list. To help you choose, we’ve put together this quick guide. Below we discuss what to look for in an air purifier, how they work, and how to use them properly.
What to Look for When Buying an Air Purifier
When selecting an air purifier for your home, it’s a good idea to watch out for the following features:
- HEPA Filtration of Equivalent
Without high quality filters, your air purifier just can’t do its job. Look out for a purifier that can remove at least 99% of pollutants from the air, and check that it can handle very small particles, such as smoke, mold spores, and bacteria.
- Efficiency
A good air purifier won’t cost you the earth to run. Look out for options that don’t consume more than 75 Watts on their highest setting, and have been Energy Star certified.
- Quiet Operation
For a quiet purifier, watch out for options with a ‘sleep’ setting, and check out the customer reviews to get a better idea of how it sounds in action.
- Good Coverage
The coverage you require depends very much on the size of your home. Look out for a purifier that can accommodate an area at least as large as the intended room.
Benefits of an Air Cleaner
Introducing an air purifier into your home comes with a number of benefits, including:
- Removing allergens such as pollen, dust, and dander from the air
- Preventing the spread of bacteria, viruses, and mold spores
- Dealing with odors in the home
- Removing cigarette smoke from the air
- Working efficiently to reduce allergies, asthma, and eczema
How Do HEPA Filters Work
HEPA stands for High Efficiency Particulate Air. HEPA filters must meet a strict standard from the Department of Energy for removing particles from the air. These standards dictate that the filter must remove 99.97% of particles as small as 0.3 microns in size.
HEPA filters were initially developed to remove dangerous radioactive particles from the air at nuclear facilities. Now, they remove pollutants, allergens, and potential pathogens from the air in your home. They work like a very fine sieve, perforated with microscopic holes that snag tiny particles, only letting air molecules pass through.
HEPA filters consist of many layers, each finer than the last, to help them capture particles of varying sizes. They’re typically made from glass fibers.
Home Air Purifier Tips: Setup, Operation, and Maintenance
If you’ve never used an air purifier before, knowing where to start can be a little tricky. Luckily, it’s pretty straight forward.
- Where to Put Your Air Purifier
To get the most out of your air purifier, place it in the room where you spend the most time. It’s a good idea to place it out of the way, where it won’t be knocked over, without blocking airflow. Avoid corners, and consider placing it on a side table of shelf for best results.
- Keep Doors and Windows Closed
When your air purifier is switched on, it’s a good idea to keep doors and windows closed. Home purifiers can only cope with so much air, and by leaving the windows wide open, you’re essentially asking it to filter the entire world. To ensure the air inside is ‘clean’ try to keep a barrier between it and the outside.
- How Long Should You Run an Air Cleaner
Air purifiers aren’t designed to be used for short stretches of time - a few minutes of filtration just won’t get you the results you want. However, leaving the device switched on constantly can eat through electricity if you’re not careful.
To find a happy medium:
- Only run the purifier when you’re in the house
- Consider running it overnight, and switching off in the morning
- Run the purifier on the lowest setting whenever possible
- How Often Do Filters Need to be Replaced
This will depend on the make and model of your device, along with how frequently you use it. Most HEPA filters will need to be changed every 6 to 12 months for best results. Luckily, many purifiers feature a handy indicator light that lets you know when a change is required.
Best Air Purifier FAQ:
Q: What is a room air purifier and how does it work?
A: Air purifiers perform an important function, but they’re actually deceptively simple. Many are equipped with complex sensors and circuitry, but the essentials are universal.
They work by drawing air through a series of filters using a fan. When air passes through, tiny particles within it are snagged and captured by the filters, which work like a microscopic sieve. Clean air is then propelled out of the device.
Some purifiers also expose the air to UVC light, which kills bacteria and viruses. Although this is a handy feature, it does produce trace amounts of ozone, which is harmful to humans. For this reason, we’d suggest using the UVC function sparingly.
Q: How long does it take for a home air purifier to work?
A: High quality air purifiers get to work in a matter of minutes. Most will clean all the air in a room after 10 to 30 minutes.
It can take a little while for your body to respond to cleaner air, however. If you have allergies, asthma, or eczema, you should notice an improvement to your condition within a month or so of using the purifier.
Q: Are air purifiers loud?
A: Generally, no. It will depend on the version you purchase, but most high quality air purifiers can run very quietly.
The noise do they produce is the result of a small fan, which draws air through the filters within. Many air purifiers have a ‘quiet’ or ‘sleep’ setting, for night time or nap time operation.
Q: How do I know if my air purifier is working?
A: Many air purifiers feature a display that helps you track the current air quality in your home. This makes it easy to tell if the device is working as it should.
Without this display, you can check that the purifier is working by checking the filter manually. If the HEPA filter appears clogged and dirty, the device won’t be working too effectively, and you’ll need to replace it for optimal functioning.
