Pollution has increased immensely in recent years. Crowded cities, smoke of vehicles, increased industrial area, green house gases increased pollution a lot. Home atmosphere is not less but more polluted than outer. Conjusted living, small houses, less open space & windows, deodrands & cleaning chemicals, even pets add more pollution to home atmosphere. If any Of The homemate is having asthma, any allergies or any respiratory problem air purifier is the solution.
If you are thinking to purchase air purifier, you should know the basic things about it.
Air purifiers are classified on the basis how they purify the air.
Ozone purifier – Ozone kills bacteria & viruses in the air. At the same time ozone is harmful to human being. So such purifiers should be avoided.
Air ionizer – It ionises the air molecules due to which bacteria & viruses stick to wall but keep alive. Sometimes these air purifiers release ozone.So these also should be avoided.
The best option is to select air purifiers with HEPA filter & better CADR.
What is HEPA & CADR?
High Efficiency Particulate Air filter is shortly termed as HEPA filters. It removes the particles of diameter .3 micron which include dust, bacteria & more. Theoretically it gives 100% pure air. HEPA filters are made up of twisted thin fibres of glass with activated carbon based material.
HEPA filters can remove the particles up-to .3 micron but it can’t remove bad smells & harmful gases. To remove this, activated carbon filter is needed. It removes toxic gases from the air. To be more accurate a pre-filter is required to remove big particles like human or pet hair, cobwebs etc.
Thus the air purifier should be combination of pre-filter, HEPA filter & carbon activated filter.
Clean Air Delivery Rate is termed as CADR. CADR shows the volume of air in cubic feet per minute purified for a certain particle like smoke, dust, pollants.Higher CADR rate shows higher purified air Generally more than 400 scale for dust, smoke & pollen is better.
CADR scale is shown like this, 320/400/450.First number denotes smoke CADR, second for dust & third for pollen.
Things to be considered before purchasing air-purifier –
Maintainance- If you use HEPA air-purifier, the duration Of The filter is 7-12 months. Filter should be replaced within a year. So first of all you should consider maintainance cost.
Power consumption – The next main thing is power consumption. As air-purifier will run more than 10 hours the energy consumption should be thought over carefully. An air-purifier consuming less than 200 watts should be preferred.
Noise – Noise level should be as low as possible to not to disturb your sleep in night. Generally a large unit at low speed should be preferred.
Automation – Some air -purifiers automatically gauge the pollution level & adjusts the speed Of The fan. Off-course these are costly.
After-sales-services – You have to replace the filters per year. So good after-sales-service is needed to install or any problem happens.
