Looking for an air purifier ?? U need to know few things about it to make a decision for yourself. Lets take a look.
It is a device made up of porous material which removes dust, pollen and bacteria from the air but filters with an adsorbent or catalyst may remove odors and gases. Hence, help with allergies and asthma. The commercially graded air purifiers are manufactured as either small stand-alone units or larger units which can cover large areas.
Two types of air purification technologies are present, active and passive.
Active air purifiers release negatively charged ions causing pollutants to attached to them, while Passive purifiers use air filters to remove pollutants. Passive purifiers are more efficient as the dust and solid particles permanently removed from the air and get collected in the filters which can be cleaned.
Other methods includes :
High-efficiency particulate air (HEPA/HVAC) filters and ultraviolet germicidal irradiation (UVGI)
Basically, air is forced through a filter and particles are physically captured.
- High-efficiency particulate arrestance (HEPA) filters remove at least 99% of 0.3-micrometer particles to larger particles. In dusty environments, a HEPA filter may follow an easily cleaned conventional filter (prefilter) which removes coarser impurities so that the HEPA filter don’t need cleaning or replacing frequently. They do not generate ozone or harmful byproducts.
- Filter HVAC at MERV 14 or above has a capture rate of 75% for particles between 0.3 to 1.0 micrometers. Compared to HEPA filter, HVAC central air system can take more air in the same period of time. Using a high-grade MERV filter can be more effective than using a high-powered HEPA machine.
- Ultraviolet germicidal irradiation (UVGI) use to sterilize air that passes thru UV lamps via a fan which force air past the light.
Best filters available in market are enlisted below. You can choose the one which suits you.
IQAIR HEALTHPRO 250
Power Consumption (W): 100-120 V, 50/60 Hz Coverage Area(sq.ft.): 800 Noise Level (dB): NA Air Flow Rate (cubic m/h):70-510m3 /h Filter Type: Hyper Hepa Dimensions: H 71 x W 38 x D 41 cm Ionizer: NA
This is a powerful air purifier that delivers better air quality in their spaces, regardless of it’s cost. It is equipped with PreMax Filter, Cell MG filter which consists of an activated carbon filter and a hospital-grade class H12/13 HEPA filter. It can cover an area of up to 800 sq ft and one can also duct the air purifier for better performance. Average air filter life is 4 years, so no need to change it frequently. It has efficiency of 99.95% which is very difficult to match as compared to others, that’s why the price is high. Price is approx. 1.2 lakh.
SPECIFICATIONS Power Consumption (W): 1.2 W Coverage Area(sq.ft.): 520 sq ft Noise Level (dB): 43 dB Air Flow Rate (cubic m/h): 408 CMH Filter Type: HEPA, Pre-Filter,Activated Carbon Dimensions: 416 X 720 X 292 Ionizer:Yes
It is highly efficient due to its H-14 grade HEPA filters and relatively average filter size as compared to others. It act using the Plasma-cluster technology that produces a plasmacluster shot which is a burst of positive and negative ions that remove fine to ultrafine particulates as well as pathogens like virus and bacteria. Hence, keeps the air free form bacteria/viruses and save you from various diseases. Price is approx. 27000.
DYSON PURE HOT + COOL
SPECIFICATIONS Power Consumption (W): 40W Coverage Area(sq.ft.): 600 sq.ft Noise Level (dB): NA Air Flow Rate (cubic m/h): NA Filter Type: 360° Glass HEPA Dimensions:20.5 x 24.8 x 76.4 Ionizer:NA
It’s a good air purifier with good brand value. Under permissible limit, it was able to reduce harmful PM2.5 and PM10 particulates . Packed with features like heated air projection, connectivity, oscillation, scheduling, auto mode and more, it makes a really convenient device for everyone. Due to the various modes and able to control the device, the price of it make you feel secure. Price is approx. 55000.
MI AIR PURIFIER 3
SPECIFICATIONS Power Consumption (W): 38W Coverage Area (sq.ft.): 484 Noise Level (dB): 64 Air Flow Rate (cubic m/h): 310m³/h Filter Type: 360-degree triple layer Dimensions: 240 × 240 × 520 Ionizer:NA
The Mi Air Purifier 3 features similar design as its predecessor but has a new OLED display to show the PM2.5 levels, temperature, humidity levels and has WIFI connectivity. The air purifier has a filter with capability of removing particulates from 0.3-0.5 microns in size and can reduce PM2.5 and PM10 levels as well. The device’s cylindrical filter is composed of three layers and comes with a pre-filter, HEPA filter and an activated carbon filter that eliminates dust, pollen and harmful gases. The device claims to have a CADR of 380 cubic meter/h and is said to be effective for rooms up to 484 sq ft. It can also be linked with the Mi Home app to enable IoT capabilities like remote monitoring and control. Price is approx 10000.
PHILIPS SERIES 1000
- SPECIFICATIONS Power Consumption (W): 50 Coverage Area(sq.ft.): 677 Noise Level (dB): 33 Air Flow Rate (cubic m/h): 270 Filter Type: Extra-thick Nano-Protect, HEPA Series 1 Dimensions: NA Ionizer:N/A
The Series 1000 is equipped with Vitashield and NanoProtect Pro (HEPA) Filter which is capable of removing PM2.5 pollutants using both of them. It can also remove harmful gases such as formaldehyde and any volatile organic compounds present in that area. Besides that it can remove pathogens like bacteria and viruses. There is a real-time air quality check on-board. It works in auto-mode if it detects change in air quality and the fan speed increases automatically. Price is approx. 9000.
