guide to air purifiers-the relief of breathing fresh air
What’s the purpose and benefits of an air purifier?
Effects of Air pollution on us
Pollution of natural resources is a reality and its effects on humankind is inevitable as it is becoming. But while some solutions to land and water pollution are there in the form of organically grown food and purified drinking water, of the many health-conscious practices that we wish to imbibe in our everyday lives, we neglect the very air that we breathe.
Rising cases of causalities caused due to the rise of air pollution in India highlight these as the most common effects of breathing in polluted air;
- Dust allergies
- Increased pressure on lungs making one susceptible to breathing difficulties
Why do you need an Air Purifier for our Homes?
The lack of awareness for air pollution has its adverse effects on all of us equally. But some of its major effects on our health can be very well taken care of, thanks to the revolutionary air purifiers.
The indoor air in our homes and offices can be up to 2-5 times as polluted and toxic as the air outdoors, primarily due to high concentrations of toxic particulate matter inside closed walls, with lack of air circulation being an additional factor. Breathing-in this air can cause a number of respiratory diseases and allergies.
Considering the fact that we can spend almost 80% of our daily hours indoors, it makes it evident that the need for clean indoor air is urgent and necessary. The lack of awareness among the public about indoor pollution is both shocking and unfortunate, but all we can do, and must do, is act before we start facing the consequences.
How does having an Air Purifier help?
The major pollutants which may affect the quality of the air inside your very homes may be;
- Seasonal pollens
- Dust and debris from construction nearby
- Incense sticks and candle fumes
- Tobacco smell and smoke from cigarettes/cigars
- Toxic fumes from paint, varnish aerosol sprays and pesticides
- Pet dander
- Dust mites and bacteria
- Mold formation in damper areas or during monsoons
- Oil and spice residue from open kitchens
The air purifier is a simple yet powerful appliance which filters out these pollutants from the surrounding places.
How do air purifiers work? They pull the surrounding air similar to how a kitchen chimney or air conditioner does. Their specially built filters work to trap the particulate matter, germs and odor, expelling out clean, sterile and fresh air.
What are the benefits of air purifiers?
Needless to say, homes with pregnant women, people with breathing issues like asthma, children and pets need air purification arrangements to be made for a healthier living. But it’ll be wrong to say that not everyone benefits from breathing in air of good quality.
Even if you don’t suffer from any breathing difficulties, allergies or experience high polluted air in your city, having an air purifier will not only ensure that you stay healthy and safe from these diseases and allergies, but also safe guard yourselves from the effects of the slow poisoning air pollution has threatened us all with.
The major benefits of air purifiers give many attractive reasons to buy one the earliest;
- Reduce the symptoms of seasonal allergies
- Avoid mold formation indoors
- Traps in microbes which may lead to infections
- Cancel-out pungent smell from pets, dampness, etc
- Removes second-hand smoke from burning tobacco
- Prevent dust
Air purifiers improve health by not just sterilizing our homes from micros and allergens. Results have shown that air purifiers help with sleep since while we’re sleeping, our breathing slows down and air purifiers reduce the pressure on our respiratory systems by providing us with pre-filtered and purified air.
choosing the right size for your air purifiers
What size of an air purifier do I need?
The popular misconception related to air purifiers is that it’s a one-size-fits-all machine. As neglected as this preliminary step while buying an air purifier might be, calculating and properly sizing an air cleaner for a room need not just be a necessary task, but also a clever one.
Having an air purifier which is cheaper and smaller for a room bigger than the devices’ prescribed square footed will waste more of your money than saving it. For instance, if an air purifier for a 300 sq. ft room area is placed in 450 sq. ft room, it will put unnecessary pressure on the appliance.
- Air purifiers with auto cut-offs won’t ever meet their expected targets and continue working on for long hours
- Estimated lives of the filters be reduced
- Air purifier will end up consuming more electricity
- Yet, you will never get your desired results
The ACR and CADR ratings on your air purifier are meant for the prescribed square footage recommended by the manufactures. If you place an air purifier meant for smaller rooms in a bigger one, neither will it be able to serve the, for example, 4x or 5x Air Change Rate, nor will be as effective as the 150/200/160 Clean Air Delivery Rate markings, for instance.
So, how to properly size an air cleaner for a room?
It is honestly very simple; just calculate the square area for which you want to buy an air purifier. For a larger open space with multiple rooms, sum the square footage of the individual rooms and now that is the minimum square footage for which you need an air purifier.
It is always wise to choose an air purifier meant for area equal to or a little larger than your calculated area, not the other way around.
air purifiers complete buying guide
13 Features and factors to consider while buying an Air Purifier
While browsing through catalogue and choosing the best air purifier to buy, you’ll notice how most of the appliances are so similar yet so different. Give attention to detail and you’ll see the different array of features present in them. Some may be gimmicky but some are very attractive and useful, turning your preferences towards them.
This Complete Guide for Buying Air Purifiers will try to briefly explain each of these features you must look for while buying an air purifier;
1. ACR ratings
Air Change Rate is a marking for the purifying capacity of air purifiers, telling you how many times an air purifier can clean the air inside a room for a specified square footage.
2. CADR ratings
It stands for Clean Air Delivery Rate and is a rating for effectiveness. It tells us about the devices’ ability in eliminating Dust, Tobacco Smoke and pollen from the air. It is usually always measured with the top fan speed of the device.
Also check out our article “Air purifier ratings: Understanding the ACR and CADR markings” for more details.
3. Air Quality Sensors
Automatic air-quality monitoring is a great feature to have in your air purifiers. It keeps a track of the level of PM 2.5 pollutants suspended in the air in live time and adjusts the program of the device accordingly.
4. Air Quality Display
This display panel will not only show the digital controls and current settings of the appliance, but will also display the live results of the air purifier’s effectiveness from the air quality sensors.
5. Noise levels
Air purifiers with fans and motor will inevitably produce some amount of noise, but it need not be a lot. Some produce so little sounds that they double as a white noise device. Do test the device for noise level before buying.
This is a very handy feature to have. It will avoid tripping over the device in the dark, and also double as a nightlight.
7. Antimicrobial Treatment
UV lamps, Carbon filter and other anti-bacterial coatings on air purifier filters help in eliminating harmful pathogen from the air we breathe.
8. Filter Replacement indicator
As useful as it sounds, this indicator will automatically detect and tell you when the filters have worn out. It is very important since disposing the filters too soon is a waste of money indeed, but using filters beyond their life not only puts load on the device while consuming more electricity, it adversely affects the life of the motors too and also adversely impacts the purifying capability of the device.
9. Maintenance Cost and After-Sales Service
Air purifier maintenance is usually a very low costing service, and they anyway don’t require frequent servicing like air conditions and kitchen chimneys. But it is wise to choose your device from a brand which provides authorized after-sales maintenance in case of need.
Having a reasonable warranty period with any electrical device is advised, and it is the same for air purifiers too.
11. Manufacturer’s reputation
Read ratings and reviews and do a thorough check on the manufacturing party.
12. Power Consumption:
In general, air purifiers consume very less energy, ranging between 50- 200 watts for proper functioning. Yet a standard procedure before buying any electrical device, opt for one which has the lowest or reasonable power consumption and most efficient electric consumption rating.
13. Handles and wheels
Lastly, having comfortable handles on the side of the appliance and wheels at the bottom will make it handy to carry the purifier or to shift it across the room.
