Air purifier Buying guide
What is PM 2.5 and PM 10
PM 2.5 stands for particulate matter. It is that suspended matter present in the air that we breathe. These liquid molecules are so small that you can’t see them as they are 2.5 sizes in microns or diameter which 30times smaller than the human hair.
PM 10 is the particulate matter which has a size of 10 microns or less in diameter. It is relatively larger than PM 2.5. One PM 10 is equal to 4 Pm 2.5 particulate matter.
Effect on the health of PM 2.5 and PM 10
We keep hearing that PM 2.5 and PM 10 are the invisible and silent killers. PM 2.5 is more dangerous than PM 10. These small particles get inside our lungs when we inhale. Short term exposure with these particles can be seen in the form of eye irritation, nose running and sneezing etc.but continuous exposure can be very hazardous to our health. It brings several health problems like –
- Lungs cancer
- Heart attack
- Early ageing
- Asthma and other respiratory diseases
- Low weight born baby
- Premature delivery
- Out of breath
- Chest pain
- Fast heart breathe
- Increased inflammation.
Do you know Indoor air pollution is more dangerous than outdoor?
Whenever we talk about air pollution we talk about pollution from vehicles, pollution coming from industries, smoke, power plants, and construction. But in reality, pollution can be two types of indoor air pollution and outdoor air pollution. Doesn’t it sounds funny that how we can talk about a different type of pollution where the air is the same we are breathing in?
Sources of Indoor Air Pollutions:-
Do you know that indoor air quality can be worse than outdoor because of the higher level of pollutants? Indoor air pollution is more dangerous than outdoor because people, especially women and children spend more than 90% of their time at home and inhaling polluted air can make you and your family get sick and serious health concerns in the long term.
The main source of indoor air pollutants is Airborne particles, Tobacco smoke, and household odours. Airborne Particles or pollutants indoors include pet dander, bacteria, virus, pollen, dust allergens and fungi which can be responsible for asthma, nausea, difficulty in breathing, eye irritation and eye-watering whereas smoking is the prime reason of cancer.
Emissions are another major factor making the indoor air polluted no matter from where it is coming. Incense sticks and cones, mosquito coils and wood/gas stoves are the main contributors for producing black carbon emissions. It reaches the lungs and brings several respiratory and heart-related problems.
Type of filter to purify the polluted air.
1. Pre Filter:-
Pre-filter is the first layer of a filter in any purifier. Polluted air first comes in contact with the Pre-filter. It catches large dust particles, pet hair, and mould and passes the air to the second filter either Hepa or any other one which an air purifier equipped with.
Pre-filter is a very essential feature of any purifier as it prolongs the life of the main filter True HEPA filter. The biggest advantage of pre-filter is that it can be washed in tap water anytime. Hence there is no need for replacement with this filter.
2. HEPA Filter:-
HEPA stands for High-Efficiency particulate air. This is an advanced filter technology used in an Air purifier to capture microscopic particles present in the air. These particles include:-
- Particulate PM 2.5 and PM 10
- Allergens & Pollen
- Mould spores
- Pet dander
- Smoke & dust
Hepa filters come in various types like true Hepa, Hepa, Hepa like and Hepa type. But there is a huge difference between them. True Hepa filter is the most efficient one and best in their category. It captures the widest range of contaminants and removes the pollutants as small as 0.03 microns up to 99.97% .whereas Hepa, Hepa type and Hepa Like has the capacity to remove particles measuring 2 microns and larger.
Highlights of HEPA Filter:-
- Highest level of purification process
- Remove small particles and do not release back into the air
- Most effective
3. Activated Carbon Filter:-
Activated carbon filter is another kind of filter used in air purifiers. This filter is responsible to absorb and filter out harmful gases like formaldehyde & VOCs, fumes, chemicals and bad odours produced from smoke and cooking. This is a small piece of carbon-containing several tiny holes. These tiny holes make the surface area of carbon larger. Hence one gram of activated carbon has a surface area of more than 32000 sq ft. Higher the surface area, better the performance of Air purifier.
Carbon filters can not capture particulates like 2.5, pollen and pet allergens. That’s why it does not come alone in any air purifier rather it is accompanied by another filter like Hepa Filter to capture other impurities like dust, lint, mould spores, smoke, other chemicals, and air particles.
The filtering rate depends on the size of the carbon filter. Bigger the carbon filter you choose, the higher the filtration rate you will get.Like Hepa filter activated carbon filter needs to be replaced once it is full of impurities.
4. Ionic Filter:-
This is a different kind of filtration system or another way to clean the air. It is called Ionic, Ionizer and ionization. These filters work on the basis of emitting negatively charged ions into the air. When these ions come into contact with positively charged ions like pollutants, airborne particles, dust, pollen, and bacteria tends to form a bond with them.
Or we can say that these ions get attached to the impurities present in the air and which makes the air polluted. It forces these impurities to cling to the surface. Ionic filter does not remove the contaminants rather it makes these air particles heavier than normal which causes them to fall on the ground.
Few Ionic air purifiers, equipped with electrostatic collection plates are able to eliminate ultrafine particles as small as 0.03 microns or diameter.
5. UV Filter or UV light:-
UV light is a kind of electromagnetic radiation like radio waves and x rays. UV filter is a kind of UV lamp inside the filter to inactivate or neutralize the airborne microbes and microorganisms like mould, spores, bacteria, and viruses.
Few Air purifiers are featured with UV light technology. There is a chamber of UV light after the main filter like Hepa Filter. The air passes through the Hepa filter first and then comes in contact with UV Light. And before releasing into the room air goes through with another filter.UV-C light is not directly released into the room hence these purifiers are properly safe for us.
What is CADR-?
CADR stands for a clean air delivery rate. This numeric value will tell you exactly how fast your Air purifier purifies the air or how much cleaned air your air purifier can deliver per hour. On the other hand, how the air purifier is effective to clean the air. If your room size is large then its better to choose an Air purifier having higher CADR.
AHAM (Association of Home Appliance Manufacturers) invented CADR. This measurement is for dust, pollen, and smoke. Hence you should look for air purifiers designed with higher CADR only for an efficient purification of your home air.
Feature you should look in an Air purifier for home
- Filter Type:- The very first thing a consumer should look at the type of filter used in an Air purifier. As we discussed above True Hepa Filter is the advanced filter technology you should go with. Pre-filter, Hepa filter, and activated carbon filter are the must-have filter an air purifier should have for better purification.
- CADR Rate:- The second next factor for the best Air purifier for home is the Clean air delivery rate which will show you how effective a purifier works. Higher the CADR, the faster it purifies the air and larger it covers the area.
- Noise Level:- Noise level depends on the fan speed. Faster the fan speed, higher the noise level. Hence fan speed should be adjustable.
- Price:- You should decide the air purifier from price and filter replacement cost too.
- Air quality Sensor:- An Air purifier must see the air quality sensor so that you can review the report of an air purifier from time to time.
- Notification of filter replacement:- With this feature, an Air purifier will notify you when its filter needs to be replaced so that you can breathe cleaned air always.
- Mobile app connectivity:- There are some purifier comes with internet integration or app connectivity through which you can control or operate air purifier sitting in any room.
- Night Mode:- This is another essential feature you should look for. Night mode enables a purifier to adjust the noise level and lights as per the sunlight.
- Child Lock:- This feature will save your children and don’t let them tamper the air purifier function.
