Studies have shown that indoor air is five times more polluted than the air outside. As we spend most of our time indoors, a high-performance air purifier would help create a healthier, cleaner environment in your home or business. In times of the pandemic, a powerful air purifier, which filters out aerosols, might be just the thing that protects you from viruses and germs.
Before we dive into our review, we’ll go through some major parameters for choosing the best air purifiers.
There are essentially two major filter types: HEPA and non-HEPA.
HEPA stands for High-Efficiency Particulate Filter, which removes 99.97% particulates as small as 0.3 microns. A good air purifier should have HEPA filters inside. These are the layers that filter out harmful particulate matters, such as pm 2.5 particles. Tiny particles less than 2.5 microns can settle in our lungs and cause breathing difficulties and other long-term diseases and ailments. For people who suffer from allergies and asthma, an air purifier with HEPA filters can help alleviate the symptoms. HEPA air purifiers can collect fine pollen and dust particles, ensuring that the symptom-triggering allergens are filtered out completely.
You may see terms like true HEPA, HEPA-like, HEPA-style when you’re choosing an air purifier. Note that these terms have no legal or scientific meaning. Some air purifiers that use these terms may still be very close or even exceed HEPA standards, while others are far behind. Look for the 99.97% particulate removal rate when shopping for an air purifier. That is the primary indicator of whether or not it meets HEPA standards.
Non-HEPA filters are anything that isn’t HEPA. These could be paper filters, plastic filters, ionizers, PECO filters, and others. However, non-HEPA doesn’t mean it will be a poor performer. For instance, if you have a newly decorated house full of VOCs (volatile organic compounds) such as formaldehyde, we recommend choosing air purifying units equipped with activated carbon filters to absorb odours and VOCs. With that being said, compared to HEPA, the non-HEPA filters generally perform worse when the models are at the same price range.
Air quality indicators
The best air purifiers have built-in air quality sensors, which can alert users on how bad or good the indoor air quality is. While some are colour-based — the indicators turn red, orange, or blue depending on the air quality, others may have a monitor that shows levels of air pollution in real-time.
Coverage area is the square foot area that the air cleaner is recommended for. For most air purifiers, the greater the airflow generated by the internal fan, the greater the coverage area is going to be.
When you buy an air purifier, one size doesn’t fit all. Keeping in mind the room’s exact size while purchasing an air cleaner is crucial. A smaller purifier may be adequate if you have a smaller space. But you will need a larger device for a larger area like a living room. The CADR (Clean Air Delivery Rate) is essential in seeing how much clean air the machine can produce. The higher the CADR is, the faster the unit filters the air, and thus the more efficient it is.
Like vacuum cleaners, air purifier filters will need to be replaced regularly. That is why you also need to consider the availability and affordability of the filters. (HEPA filters last about one year. Activated carbon filters typically last six months. Pre-filters generally 3 months, but some filters are washable for long-term filtration.)
Your air cleaner may be running the whole day. So you might want to pay attention to the energy consumption level.
As it may potentially affect your sleep, how much noise the purifier produces while functioning is also a major parameter that you should look at.
App connectivity & smart home integration
In digital era, smart air purifiers has become trendy. App connectivity in an air purifier could be used to turn on or shut down the device when you’re not home. You can even connect all smart home appliances and control certain elements right from the phone. These factors are nice for many consumers and help make the purifier more convenient. However, they will not dramatically impact the purification performance in most cases.
To summarise, to qualify as a great air purifier, the device needs to be powerful enough in its purification features, quiet enough for you to sleep at night, and reasonably priced.
Based on the features mentioned above, we’ve picked a couple of models as our recommendation for you.
Best air purifier for large coverage area
It’ s one of the best performing, most durable and economical purifiers we’ve tested. It’s ideal for purifying large rooms, small homes and apartments up to 108 square meters.
Effective, efficient & inexpensive

The JA-1706/1806 uses a 3-point air filtration system:
- HEPA H14 Filter
- Nanocrystalline filter
The pre-filters are responsible for capturing large particles in the air and can be easily cleaned by rinsing.
The HEPA H14 filter is the primary filtration system, trapping air particulates as small as 0.3 microns at the rate of 99.995%. (Performance verified Intertek, an independent, third-party, internationally recognised testing laboratory)
The nanocrystalline filter eliminates VOCs and reduces odours.
The main item of maintenance needed is to replace the HEPA filters. JA 1706 has a filter change reminder that tells you when to replace the HEPA filters.
Otherwise, you will need to occasionally clean the pre-filter, which can be vacuumed or machine washed as needed.
We would recommend the JA 1706/1806 if you’re looking for the following features:
