Buying Guide: A Complete Guide to Air Purifiers

The indoor living spaces where we spend most of our time is more or less equally polluted than the outside air in reality.

Since indoor areas are mostly closed living spaces, it is harder for these impurities to escape outside on its own leaving it polluted with microscopic pollutants such as dust particles, bacterias and allergens such as pollen dust.

Thus it becomes necessary to have an air purifier inside the room, especially in tropical countries like India which remains dry and dusty all year round.

Whether you are in your home or office, using an air purifier can easily solve these poor air quality issues. With the best air purifier, you can be assured of a healthy living environment.

But, picking up the right purifier that fulfils your needs is something tricky. Choosing the right one that fits your requirements is a daunting task indeed.

We hope this buying guide will cover a few important aspects to check while buying an air purifier and will help you make a learned purchase decision.

Major types of Air Purifiers

Mainly there are two types of air purifiers available in the market.

1. Room Air Purifier: These are the indoor air purifiers used for cleaning the air in living areas such as bedrooms, living rooms, office spaces etc.

2. Vehicle Air purifier: Vehicle air purifiers have a highly compact design that fits inside the passenger cabin and is capable enough to clean the pollutant air, dust, and allergens that is present in the inward flowing air.

Features to look out for while purchasing an air purifier

Once the type of air purifier you need is fixed, the next thing to consider is the special features that might be suitable for your particular requirement – such as the volume of air space to be cleaned, energy consumption, portability, smart connectivity etc.

  • Look for the air purifiers having the energy star rating by the EPA. This helps in saving a significant amount of money by consuming less power to operate.
  • Wi-fi air purifiers: The air purifiers come with wi-fi connectivity, which can easily be controlled from the user’s phone via an app.
  • Air quality indicators: To monitor the real-time quality of the air, pick the air coolers which update the real-time air quality in the room either as a digital LED readout or as a variable colour indicator.
  • Caster wheels: The multi-directional castor wheels aid in better portability and helps you to move the air cooler quickly and easily across the room.
  • Carry handles: Most of the portable air purifiers come with enough heft to carry around. If you are planning to shift the air cooler from one place to the other, choosing a device with a handle will be helpful.
  •  Remote control: This feature helps the users to adjust the settings from across the room without having to be physically in contact with purifier whenever you need to change some settings such as fan speed.
  • Washable Pre Filters: These filters are reusable, and can be washed and used multiple times.
  • The washable filters act as a protective shield over the primary filters that in turn helps the users to save money on primary filters.
  •  Filter change indicator: It is highly advised to purchase air purifiers with filter change indicators. This indicator will flash when it’s time to clean or replace the filter.

For an air purifier to deliver its maximum performance, the filter demands a regular change or clean up.

  • Air Change Rate (ACH): This rate shows exactly how many times the air purifier filters the air in an entire room in an hour. The more the ACH, the better will be the purification rate.
  • CADR Ratings: This rating is all about the efficiency of an air purifier and how quickly it works. Here, the filtration rate is considered in cubic feet, that in one minute, how many cubic feet of air gets filtered. For Large-sized rooms, consider air purifiers with higher CADR ratings.

Air Filter Types

There is a wide variety of filter technologies with a common goal, ie; to filter the air out of the smoke, dust, and other harmful pollutants.

Some of the most commonly used air filters are as follows:

  • HEPA (High-Efficiency Particulate Air) Filters

HEPA filters designed to clean the allergens like common dust, pollen, mould spores, dander, and animal hairs.

HEPA filters can clear up to 99.9% of the harmful particles which are as small as 0.3 microns.

The material, size, and construction of a filter matter. The larger the filter size, the more will the purification rate.

  • Antibacterial and Germicidal Filters

Along with the HEPA filters, using VU filters eliminates dreadful germs and harmful bacteria which keeps the air highly purified.

The air purifiers that have antibacterial and germicidal filters are mostly used in the labs, kitchens, daycares, and hospitals to minimize the spreading of air-borne infections.

  • Activated Carbon Filters

The activated carbon filters are used either by itself or often can be seen as a combination along with other filters.

Activated carbon/charcoal filters perform well in absorbing the harmful gases, odours, chemicals, fumes, and smoke.

This filter reacts with oxygen to form millions of pores by which a large amount of gas and odours gets trapped.

  •  Photocatalytic Oxidation (PCO)

PCO is made out of a titanium dioxide-coated metal plate paired with the UV light and the filtration process is carried out by breaking down and oxidizing the chemical molecules.

This filtration can make large-sized molecules break down into water molecules and harmless carbon dioxide.

  • Charged Media Filters

This is a combination of particle filter along with an electrostatic charge filter, that captures small particles of 0.1 microns to perform efficient air purification.

  •  Pre-Filters

Pre-filters are the filters used to trap large particles like pet hair entering it to the main filters.

The lifespan of these purifiers can be boosted by replacing them regularly.

  •  Electrostatic Precipitators

This filter is similar to the charged media filters, capturing the particles and additionally, the electrostatic precipitates make the particles precipitate and get accumulated on the collector plates.

These filters do not need to be replaced as they can be washed and used for a long time.

These are some of the important technical aspects that you should be aware of before purchasing an air purifier.

It is easier to get duped by just going for the numbers or the price, so it’s always better to make a learned decision knowing full and well about your requirements and the features that a particular purifier can deliver.
