Air Purifiers

Air purifiers will remove many common irritants from the air, improving indoor air quality and helping those with allergies and asthma manage symptoms. With hundreds of air purifiers to review, it can be difficult to know which one will suit your needs. Keeping these factors in mind will help you find the best air purifier that fit your requirement and budget.

CADR in Air Purifier

Clean air deliver rates, or CADR, measure the maximum room size a filter can clean effectively. Many units will list both a maximum and a recommended size based on how often all the air in a room is cleaned per hour. The larger the room, the fewer times the air is cleaned. Units that can handle large rooms tend to be large themselves. Standard units work well in bedrooms while mini air purifiers are ideal for bathrooms and small office spaces.

HEPA Filtration of Air Purifier

High efficiency particulate air filters, better known as HEPA filters, offer the most effective filtration for homes. To qualify for a HEPA rating, a filter must capture at least 99.97% of airborne particles larger than 0.3 microns in diametre, including dust, many bacteria and allergens.

HEPA filters are rated on a scale from E10 to U17. The higher the number, the more effective the filter. An E10 filter will provide healthy air for most households. Asthmatics or those with severe allergies should consider a more efficient filter.

Noise Levels of Air Purifier

Many air purifiers boast having "whisper-quiet" or "near-silent" operation. To test their claims, look for a decibel level rating. Most "quiet" filters run between 30 decibels on their lowest setting, which is indeed a whisper, to 65 decibels on their highest setting, the same volume as conversational speaking.

Ionisation function in Air Purifier

Ionising air filters add a negative charge to air particles. The charged particles attract dust, pollen and other irritants, making them easier for the filter to eliminate. Despite their previous popularity, ionising filters have come under scrutiny. Ionic filters often release ozone as a byproduct, which can irritate the lungs. Anyone with a respiratory condition, including asthma, should avoid ionic filters.

Bonus Features

Purifiers come with an enormous range of bonus features. Multiple fan speeds, automatic timers, nighttime modes and filter change indicators are the most common. Some good air purifiers will automatically adjust based on the amount of dust they sense in a room. Others have the option to filter VOCs, or volatile organic compounds, toxic gases released by common household items, or kill pathogens using a UV light.

Air Purifier Maintenance

Air purifier filters come in two types: replaceable and washable. Replaceable filters need to be switched out often but are more efficient. Washable filters must be cleaned periodically but will last for several years. Be wary of claims that the filter never needs to be replaced. Even washable filters will have to be switched out every few years. The purifier housing will also need to cleaned periodically, and some models are easier to clean than others. The best air purifier for your household will offer you a good balance of benefits to maintenance.
