Air Purifier Buying Guide India

Here are a few things that we considered while choosing the best air purifier for home in India such as:

1. Types of Air Purifier Filters

The efficiency of an air purifier largely depends on the type of filters used in its mechanism.

There are 6 popular air filters you usually see in a home air purifier, such as:

i. Pre-Filter:

These are found in all air purifier machines and it acts as the first line of defense against the impurities.

The pre-filters are usually made of foam or non-woven polyester material.

They can trap larger particles like animal hair, dust and other impurities very easily.

The pre-filters can be cleaned, washed and reused multiple times or as long as the purifier lasts.

ii. Activated Carbon Filter:

A single pound of activated carbon has around 60 to 150 acres of surface area, which means the larger the filter, the longer and better its working efficiency.

Their sole responsibility in an air purifier is to eliminate the VoCs and absorb the bad odor caused by obnoxious gases and other materials.

The carbon filters can’t be cleaned like the pre-filters and need to be replaced when it they are full.

iii. HEPA Filter:

HEPA stands for High-Efficiency Particulate Arrestance/Adsorption/Air.

Its main job is to trap the dust, dirt and other allergens as small as 0.3 microns and minute particles as small as 0.1 microns with up to 99.97% efficiency.

These HEPA filters could also remove the PM 2.5 particles inside your home, office and car.

HEPA filters are the most efficient filters and all the above listed air purifiers come with HEPA air filtration technology.

iv. Ultraviolet Light:

UV light technology is beneficial in destroying the bacteria and other pathogens present in the air.

Instead of just filtering them, the ultraviolet light uses the electromagnetic radiation to break the bonds in their DNA and kill them completely.

It is recommended to get an air purifier with HEPA, Activated Carbon Filter and UV Light Filter combination as it could remove all the possible air contaminants and provide you with safe air to breathe inside your house.

v. Ionic Filter:

The Ionic filter or Ionizer sends -ve ions into the air which attracts the +ve dust & allergens and make them fall down due to overload.

They also remove any smoke or foul smell from the air.

They can eliminate ultra-fine particles as small as 0.01 microns.

vi. Ozone:

Ozone air filters produce Ozone gas (O3), which is unhealthy for the environment as well as the people who consume the air treated with ozone.

So, please stay away from any device with ozone filer.

2. Size of the Air Purifier

The efficiency of an air purifier also depends on the size of your room and where it is placed.

So, it is highly advised to measure your room where you wanted to place the device beforehand so that you can pick the right air purifier that works well.

First, measure your room in square feet using the width and length values respectively.

Say for example, if your bedroom size is 10 feet width x 20 feet length, then the total square foot would be 10 x 20 = 200 sq.ft.

Likewise, if you wanted to use the same air purifier for multiple connected rooms like the dining hall, living room, kitchen room etc.., then you’ll need to add all the measurements together in square foot.

And, now that you’ve your total square foot value, you should choose the air purifier with the desired sq.ft rating to get the maximum cleaning efficiency.

3. CADR and ACH Ratings

For any air purifier machine, you’ll see two values like the ACH and CADR ratings.

The CADR stands for Clean Air Delivery Rate, which determines the efficiency of an air purifier.

CADR RatingImpurities
0.5 to 3 micronsDust Particles
0.10 to 1 micronsTobacco Smoke
5 to 11 micronsPollen
Remember that the air purifiers with higher CADR rating have faster cleaning efficiency.

The ACH stands for Air Changes Per Hour, which is usually ignore by a lot of people, but helps understand the purifier’s efficiency.

It is usually shown using X denominations such as 4X, 5X, 6X etc…where X represents the hour.

Say for example, if your air purifier shows 5X, it means the polluted air inside your room is trapped and then recycled within 5 hour interval.

The higher the ACH rating/number, the better the efficiency of the purifier.

So, thumb rule here is that both the ACH and CADR ratings should be higher for maximum cleaning efficiency.

4. Smart Features & Technologies

i. Air Quality Sensors:

The air purifiers with air quality sensors will be able to monitor the air for any pollutants and then adjust the filtration mechanism to eliminate those particles from the air immediately.

ii. Adjustable Fan Speeds:

The greater the fan speed, the faster the cleaning process would be.

Most air purifiers have 2 to 5 fan speed settings and some even come with Turbo speed option.

iii. Programmable Timers:

Thanks to the automatic turn off timer feature, you can have undisturbed sleep without worrying about the air purifier running all the night, which further saves a lot of electricity too.

iv. Filter Replacement Alarm:

The filters such as the activated carbon filter or HEPA filter need to be changed from time to time.

And, the filter replacement indicator alarms you to wash or change the filters to get the best cleaning output.

v. Plasma Wave Technology:

This is a better alternative to the Ionizer, which doesn’t emit any -ve ions into the air and instead uses the water vapor to bring the contaminants to the ground.

vi. Remote Control or Smartphone App:

Most branded air purifiers usually come with Smartphone connectivity option using which you can control the device wirelessly.

Whereas the budget models do have a remote control to operate the air purifier.

vii. Silent Mode or Night Mode:

The Night mode option allows the air purifier to work silently, which is especially a great feature during the night times when everyone gets to sleep.

You should definitely see that the night mode option exists in the air purifier that you’re selecting.

viii. Photocatalytic Oxidation (PCO):

It comes equipped with UV light technology in order to destroy the bacteria or other VoCs completely.

ix. Antimicrobial Treatment:

The antimicrobial coating on the air purifiers help prevent the spread of bacteria or other microorganisms inside the device and it helps in increasing the filter’s lifespan.

x. Transportation Wheels & Handle:

While the carrying handles help lift the device, the transportation wheels (casters) come handy while moving the air purifier between the connected rooms.

See that your air purifier has at least one, if not both.

5. Best Air Purifier Brands in India

The most popular air purifier brands in India are:

  • Dyson
  • Philips
  • Coway
  • Xiaomi (Mi)
  • Honeywell
  • Sharp
  • Glen
  • Kent

6. Cost of an Air Purifier

The price of an air purifier in India for home starts from Rs.5000 and goes up to Rs.50000, depending up on the features, area coverage requirement and brand name.

While you can get a budget air purifier like the Mi 2C with basic features for around Rs.7000, the high-end modes like Dyson Tower Air purifiers costs between Rs.30000 to Rs.40000 and they have WiFi and Smart connectivity features as well.

So, it is up to you to decide how much you’re willing to pay for an air purifier.

7. Maintenance & Support

i. Cost of Maintenance:

With regular cleaning and proper maintenance, your air purifier will function efficiently without incurring any additional costs in terms of repairs.

However, the HEPA filter and Carbon filter needs replacing once in an year, which requires some budget, which varies according to your brand.

ii. Noise Levels:

Most air purifiers come with a fan, which sucks the polluted air into the filter and releases the clean air back into the room.

As a result, you’ll hear a lot of sound from the air purifier.

However, you can slow down the fan speed to low while sleeping to reduce the noise levels.

Some popular models do come with dedicated night mode option that automatically reduces the noise at night times.

iii. Power Consumption:

For maximum efficiency, it is recommended to run the air purifiers 24/7, which consumes a lot of electricity.

The average power consumption of an air purifier is 50 to 200 watts.

And, choosing the air purifier with higher energy star rating will help save your electricity bills.

iv. Manufacturer Warranty:

Electronic appliances usually come with lot of bugs (issues) that can be rectified by the manufacturer for free under the warranty or contract period.

And, only the top brands provide better after-sales service.

So, it is advised to choose only the top air purifier brands with good after-sales support and longer warranty period.

Though they seem to be a bit expensive than the cheaper models, you’ll save a lot in terms of future issues and repair costs.
