Buying guide: Air purifiers
Because of their recent rise in popularity, the air purifier market has been flooded with hundreds of models. Check out the buying guide below for some tips and pointers to find the right one for your needs.
Factors to consider while shopping for an air purifier
Here is a list of features you should consider when choosing an air purifier for your home:
Size and coverage area
From mini wall plug-in models to huge units designed for whole house air purification, air purifiers come in a vast range of shapes and sizes.
One of the first steps when selecting an air purifier is to consider the size of the room you want to filter air in. Or, if you want a portable unit that you can use all over your house, the size of the biggest room. Once you have this measurement in square footage, choose an air purifier with adequate area coverage.
The second most important consideration of any air purifier is its filtration system. The best air purifiers contain multiple-stage filtration systems that can target all sorts of air pollutants.
For optimum air filtration, we suggest getting an air purifier consisting of at least a pre-filter, HEPA filter and carbon filter.
The pre-filter removes bigger and visible pollutants that can damage the internal fine filtration layers. Next, the air passes through the HEPA filter that traps smaller particles. Lastly, the carbon filter absorbs the gaseous molecules that cause various odors lingering around the room.
There are other filtration techniques as well, especially for targeting germs and airborne viruses, but we believe the three-stage filtration system to be the most essential of an air purifier.
ACH and CADR
Air change per hour, or ACH, is the number of times an air purifier can clean and change the total volume of air in a room per hour. The higher this number, the more efficient the air purifier. Aim for getting a unit that delivers at least four air changes within an hour.
Clean air delivery rate, or CADR, is the measurement of air volume that an air purifier can clean at its highest speed. The higher the CADR, the faster the rate of air purification.
Be warned, an air purifier can be a noisy household appliance. While the noise won’t bother you much during the day, a high noise output can disturb your evening slumber.
So, if you are getting an air purifier for night-time usage, be sure to get one with low noise output. Look for a model that features a sleep mode or emits under 40 or 50 decibels of noise.
Getting the most out of your air purifier
Here are some tips that you can follow to make the most out of your air purifier:
Clean or replace the filters of your air purifier regularly to keep it functioning efficiently
Place the unit in a room where you spend most of your time, or that is central within your home
Place the air purifier in a way so that nothing obstructs its airflow
For optimal noise levels, run the device at full speed when the room is empty, and lower the speed when occupied
Types of filters used by air purifiers
A multi-stage air purifier is a very useful appliance in any household, especially if any of your family members have respiratory problems. These are the various types of filters commonly used in air purifiers.
Washable mesh filters
These filters are usually incorporated into air purifiers as a pre-filter. They act as the first filtration stage that prevents larger particles from making their way into the other finer filtration stages. They are designed to trap visible air pollutants such as dust, lint, fiber, hair and more.
Unlike disposable filters, these filters are washable in nature and can be used repeatedly, making them economical and eco-friendly.
The HEPA, or High-Efficiency Particulate Air, filters are recommended by the US Department of Health for their ability to remove up to 99.97% airborne particles. They provide the highest protection for your home by removing the smallest of microbes and allergens, including mold spores and bacteria.
These air filters are disposable and can last anywhere between three to six months before needing replacement.
Activated carbon filters
Where mesh and HEPA filters are effective at removing solid particles, activated carbon filters are apt at capturing gaseous odor molecules. Their primary job is odor removal, hence they are usually paired with other types of filters for comprehensive air purification.
Carbon filters have a longer lifespan than HEPA ones. You’ll need to replace one of these every six to twelve months.
The mechanical filtration stages we described above do little against germs, which is why many air purifiers boast UV filters. They are essentially lamps that emit a short-wave ultraviolet light to kill bacteria and viruses. When the air passes through the unit, the UV lamp disinfects it with germicidal radiation.
Despite their amazing functionality, UV filters are somewhat costly to replace.
Indoor air quality is about two to five times worse than fresh, outdoor air, depending on where you live. A good air purifier can help you and keep your family breathing cleaner, safer air. Not only does it remove and trap airborne pollutants, but it also helps keep lingering odors at bay. Above, we reviewed the best air purifiers of 2022. We hope these products and the detailed buying guide help you identify the right air purifier for your home or other indoor space.
