If you had to clean out the air filters on an air-conditioner, you would know how filthy the air around us is, especially so if you live in the city.
But what if you have no need for an air conditioner in moderate climate and would still like clean air at home, here are some of the best air purifiers with HEPA filter.
Purifying the air around you helps you breathe easier, particularly if you have asthma, hay fever and other breathing conditions.
Not only do these air purifiers remove dust particles and bacteria from the air, it also remove allergens such as pet hair and pollen, a great way to manage your allergies.
How Does Air Purifiers with HEPA Filters Work
No different to an air conditioner, that sucks and blows out air in a room to circulate and clean it minus the cooling or heating part, the air purifiers here typically follows these steps:
- A quiet fan pulls room air into the unit, circulating and filtering the air several times an hour.
- The air then passes through a first stage particle filter*, sometimes known as the pre-filter that removes hair and dust particles.
- It then goes odour absorbing pre-filter* to help reduce unpleasant odours and capture large particles like dust, pet fur or lint.
- The air passes through highly effective HEPA filters* that capture nearly 100 % of smaller particles.
- Finally, cleaner, fresher air is released back into the room.
* different manufacturers have different filter configurations but all air purifiers featured here come with HEPA filter.
A good way to judge the efficiency of an air purifier is to look at the Clean Air Delivery Rate (CADR) index. These are typically published by the manufacturer. Where available, we have highlighted this in the list below. Higher CADR index meant more air gets passed through the unit producing more clean air faster.
