Air purifiers feel out of reach for many households, in terms of affordability. In India, they are often priced at anywhere from Rs 5000 to Rs 30,000 (roughly $50-$300). While looking for an affordable option, I came across this Indian brand called Airth. They are providing a cheaper alternative with an unbelievable pricing of Rs 2100 (under $25). In this article, let’s examine the feasibility of the product. We’ll also explore a DIY solution that would roughly cost the same.
Why the Need for Air Purifiers?
Air pollution is a cause for concern in India, particularly in regions around the National Capital, Delhi. The condition especially worsens from October to February, which is also the winter season. With AQI levels reaching beyond 400 and dense smog during early mornings and nights, outdoor activities can be hazardous and are discouraged. And as far as indoor use is concerned, the use of an air purifier has become somewhat of a necessity.
The Airth Cooler Air Purifier
The Airth product is an air purifier for the cooler. It is designed to turn any standard air cooler into an air purifying system. This is India’s first such filtration solution. It was designed in IIT Bombay and IISc Bangalore using FILTRIX Technology. The founders have also featured other Airth products on Shark Tank India. Below are the steps to install the Airth Cooler Air Purifier.
1. Remove the inlet grill from the cooler.
2. Then remove the mesh filters and clean the inlet grill.
3. Install both the Airth Cooler Air Purifier. It is a possibility that they might not fit, so fix them in place using tape.
4. Put the inlet grill back on, and make sure there are no air leakage passages. If there are, seal them using tape.
5. Switch on the cooler, since you don’t need cooling in the winter, and put the cooler in ‘Fan’ mode.
It covers an area of approximately 450 sq ft and has a CADR of 300 CMH. It lowers the room’s AQI to under 100. The company also claims the filter will last 8 to 12 months before needing replacement. The package includes 2 HEPA filters that not only block PM 2.5 and PM 10 particles but also submicron particles.
Trying the DIY Solution
We also tried the DIY solution and built an air purifier at home. It costed us roughly the same as the Airth Cooler Air Purifier. You watch this Instagram reel for further details. Below are the steps to make it.
1. Firstly, you would need a cardboard box, an exhaust fan, a HEPA filter, tape, and scissors or a cutter.
2. Cut one side of the box according to the dimensions of the HEPA filter. You have to make a slot for it.
3. Now set the filter inside the box.
4. Make sure all the edges of the box are sealed. Use tape for this.
5. Now make a hole for the exhaust fan and place it on top of the box facing inside. Using a glue gun or double-sided tape, place the exhaust fan so there is no air leakage.
6. Your homemade DIY filter is ready to use. Connect the exhaust fan to a power outlet to make it work.
Keep in mind that neither of these solutions is ideal for large rooms. There is also no AQI display to check its effect, unless you have separate equipment or a monitor.
FAQs
Q. What if I don’t have a cooler? What’s the solution then?
Airth also has a similar product for ACs that comes at a similar price point. You can also try the DIY solution mentioned above.
Q. Do air purifiers increase electricity consumption?
Most air purifiers have a small, low-wattage fan, along with basic electronics. It consumes electricity equivalent to a ceiling fan, and you won’t notice any major increase in your electricity consumption even if you run it for longer hours.
Wrapping Up
The air pollution situation doesn’t seem to get any better from here, and using such measures has become a necessity. The Airth Cooler Air Purifier can be a great starting point if you haven’t used an air purifier before. Keep in mind that this would provide you with basic protection. It is not a replacement for a conventional Air purifier. However, at this price point, it’s great for students or people living in rented places.
