Studies show that in a population chronically exposed to air pollution, even 2-day purification of indoor air can improve cardiopulmonary health (Journal of the American College of Cardiology).
Yes, you can leave an air purifier on all night safely – they are designed so that you can use them continually if you wish. It will give you a better night’s sleep as you will be breathing clean, purified air.
It can take from 45 minutes to 3 hours, and it is influenced by various aspects, including room size, power settings, filters and rates of air changes per hour.
An air purifier is good for you if you have respiratory issues, allergies or asthma, pets at home, if you smoke (or live with a smoker) or live on a busy street or around construction.
Air purifiers are excellent for providing you with a better quality sleep as you will be breathing clean, purified air. This will be most appreciated by those with allergies, lung conditions or sleep apnea. Or if you struggle to fall asleep, it will be more easily induced in a cleaner, more comfortable environment.
An air purifier would be the most effective 3 to 5 feet off the ground near the worst air pollutants (e.g. smoke, odour, mould source). Areas with lots of airflow will enable it to be most effective since the moving air lifts up dust, mould and other particles. Avoid placing it in a corner or areas with high humidity (e.g. bathroom, cooking area).
Air purifiers will significantly reduce dust in a household. HEPA filters remove up to 99.97 percent of allergens such as dust.
When used correctly, it can help reduce airborne contaminants, including viruses, in a building or small space.
HEPA filtration efficiently capture particles the size of (and far smaller than) the virus that causes COVID-19. By itself, HEPA filters are not enough to protect people from COVID-19, but when used with NHS guidance, filtration can be part of a plan to reduce the potential for airborne transmission of COVID-19 indoors.
We would recommend not to wash or rinse them as some of the fibres can be broken or stretched out, which prevents your filters from functioning effectively.
The main difference is the filtration efficiency. The HEPA-type filter has a 99% efficiency rate, whereas the True HEPA filter has a 99.97% efficiency rate.
