Conclusion

What to consider when deciding on an ideal Air Purifier for our Large Room

Everyday pollution levels are spiking up. This makes the air we breathe susceptible to pollutants and harmful pathogens and germs. Statistics for people suffering from allergic and asthmatic conditions have increased considerably making the use of the purifying devices a useful and life-saving routine and keeping these problems under check.

Therefore, selecting the right and ideal purifier for your large room is of importance. Having prior knowledge before making that purchase helps a lot. Therefore, I list a few factors to consider before making a final decision on what to go for

Room Size

All air purifiers have an optimal room size under their specification. Before making deciding on what to settle for first calculate the area in square feet of the room or space you are targeting for air cleaning. It is advisable to go for an air purifier that has an equal specification to your room or even a slightly higher specification.

The air purifiers are also bulky items thus of importance to consider beforehand the space that you are likely to place or mount it

Filter Type

HEPA is the most used filter. It can filter 99.97% of airborne particles with a size of 0.3microns such as pollen, dust pet dander, smoke, and mold. For people with allergies, they must ensure the HEPA filter is part of the present specifications.

Activated Carbon Filter removes cooking odors, while the one with Antibacterial coating works on bacteria and germs. A washable pre-filter increases the life of an air purifier. Also, check how often it takes to replace the stated filters and whether the filters are readily available

CADR Rating (Clean Air Delivery Rate)

This is a rate that tells you how efficient and quick the purifier works. It measures the cubic feet of air that the purifier can filter in one minute for a different set of pollutants. CADR goes hand in hand with the room size. Another factor to consider is Air change per Hour ACH which gives the value of times the air purifier can clean air on its acclaimed area of coverage.

Noise and Energy Rating

Before making that final decision check for that noise level rating. A high value of above 55 dB will be a disturbing noise that may interfere with your sleep pattern especially during the night Most purifiers also come with energy rating stars. Ensure that you check that for better consumption of your electricity.

Another factor to consider is convenience, cost of buying and maintenance, technology types, product dimension, warranty period, weight, included components, and energy consumption rati
