Air Quality In India is degrading at an Alarming Rate.

Increasing industrialization in combination with rapid urbanization and the burning of fossil fuels has further led to increased air pollution. But the increasing disposable income, the changing lifestyle and the increased awareness about the deteriorating air quality have bought air purifiers in the spotlight. In addition, the falling prices for air purifiers have attracted much consumer attention lately.

If you are considering buying an air purifier and are looking for the best air purifier in India in 2020, you should read this article until the end.

Read the following statistics to measure the severity of air pollution:

  • 13 of the 25 most polluted cities in the world are in India
  • 4 million school children in India have developed irreversible lung damage from toxic air
  • Indoor air pollution can be 10 times more toxic than outdoor pollution

As air pollution rises dangerously worldwide, air purification technology is becoming a dominant factor in the world market. High indoor air pollution in India is usually attributed to burning an incense stick, mosquito coils. In addition to emissions from cooking and pet dander.

The main task of the air purifiers is to remove harmful elements in the air that can lead to breathing problems. Below is an exhaustive list of pollutants that indoor air purifiers target:

  • Pollens
  • allergen
  • Dust
  • mites
  • Mold
  • Soot
  • Smoke
  • Pet dander
  • fungus
  • Germs
  • bacterium
  • viruses

But the biggest problem today is that with so many options on the market it is a challenge to find the right air cleaner for your home. For many people, air purifiers are difficult to understand and for good reasons too. There is nothing wrong with that, because every air cleaner uses a different method to clean the air and this can cause problems in choosing the right one.

In this buying guide, we tell you 7 important points to consider before you buy an air cleaner.

But before that if you are looking for recommendations about Air Purifiers, here are some:

Know the level of indoor air pollution

The first thing you need to do before you purchase an air purifier is what the level of indoor pollution is at your home. Because you may not need an air cleaner. But the subways and major cities in India suffer from pollution problems, so it is very likely that indoor air pollution would be high. If you often use incense sticks and mosquito coils, indoor air quality would be poor. In such a scenario, you would probably need an air cleaner to improve air quality. In addition to these, there are a few other scenarios that make the use of an air purifier mandatory

  • Recurrent attacks of seasonal allergies
  • Aggravating asthma
  • Presence of pets
  • House renovation
  • Proximity to industrial / production units

So if you have one of these circumstances, you should consider buying an air purifier. But if you live in a small town or village or in a suburb of a city without proximity to the industrial plant, you can probably work without an air purifier.

Choose the right filter technology

Filters are the most important decision criteria for selecting an air purifier. Different purifiers have different purification mechanisms. Four most used air filter technology are:

  1. HEPA filtration
  2. Ionic filtration
  3. Carbon filtration
  4. Photocatalytic filtration

Your air cleaner would, therefore, use one of the four mechanisms. A more detailed operation of each filtration with its advantages and disadvantages is given in the following section.

Many air cleaners nowadays come with pre-filters. Pre-filter is usually the first filter layer that is applied before the main filter to remove large dust particles from the air. These are general filters that do the basic work of removing animal hair, dust, and larger microbes. They are generally made from nylon or foam and are usually washable. So it is good to have an air cleaner with a pre-filter.

It is also recommended that filters be cleaned/replaced regularly, depending on the type of filter used, because any type of air cleaner does not work properly if the filter is clogged and dusty. If the filter is ignored for a long time, it may not work at all. Let us now look at those four important filtration mechanisms in more detail.

HEPA filter

HEPA filter is the most important filter class. They are very efficient at removing pollen, mold spores, mold, dust, pet dander, hair, mold spores, and visible smoke. Microns are one-millionth of a meter. In fact, people can see nothing less than 10 microns.

Beware of the products that claim to be HEPA-type / HEPA-like / HEPA-style because they do not meet strict standardization and may not have been tested in independent laboratories. True HEPA filters are classified using the five letters A through E, based on how well they capture particles and resist airflow.

Type A is the least effective, but still meets the fundamental criteria for HEPA, while type E (on the other side of the classification) are military-grade filters that can handle even radiological, chemical or biological particles. Based on the combustion properties, they are also classified as fire-resistant (type 1) or semi-flammable (type 2).

Ionic filter

The ionic filter works by emitting a cloud of charged ions in the air that reacts with contaminants in the air. The main advantage of the ionic filter is that it can capture ultra-fine particles with a size of 0.01 microns. They are usually washable and do not need to be replaced for very long.

Although ionic filters have a lower replacement cycle, it takes longer to clean the electrostatic filter. Because these filters use static electricity, particles that fall through this filter remain in the pipe. This accumulated dust is difficult to clean because it is ionically charged and tends to stick to the surface.

Active carbon filter

Active carbon filters are granular or powdered pieces of carbon that have been treated to be extremely porous. Carbon filtering uses a bed of activated carbon to remove contaminants and impurities, using chemical adsorption technology. These filters are mainly used to remove the abundance of dangerous impurities, such as:

  • Smoke
  • Chlorine
  • sediment
  • pesticides
  • herbicides
  • Volatile organic compounds (VOCs)
  • Odor

Most new air cleaners now come with an active carbon filter and it is imperative to have an active carbon filter, given the natural ability to retain the impurity.

When a UV light shines on the titanium dioxide, electrons (negatively charged particles in atoms) are released on the surface. It is the electrons that do the useful work to filter the air.

The electrons react with water molecules (H2O) in the air and break down into hydroxyl radicals (OH ·), which are super reactive, short-lived, uncharged forms of hydroxide ions (OH−). These small hydroxyl radicals then attack larger organic (carbon-based) contaminating molecules, causing their chemical bonds to rupture.

Post-reaction contaminating molecules are converted into relatively harmless chemicals such as carbon dioxide and water. This is a classic example of oxidation and therefore certain air cleaners that work in this way sell the filtration as PCO technology (photocatalytic oxidation).

Photocatalytic filter

Many air purifiers and ACs are supplied with a photocatalytic filter. The catalyst in the photocatalytic filter that cleans the air is typically titanium dioxide, which is nothing but a semiconductor (such as silicon). It is powered by ultraviolet (UV) light – a short-wave light from the electromagnetic spectrum that our eyes cannot see.

When a UV light shines on the titanium dioxide, electrons (negatively charged particles in atoms) are released on the surface. It is the electrons that do the useful work to filter the air. The electrons react with water molecules (H2O) in the air and break up into hydroxyl radicals (OH ·), which are super reactive, short-lived, uncharged forms of hydroxide ions (OH -).

These small hydroxyl radicals then attack larger organic (carbon-based) contaminating molecules, causing their chemical bonds to rupture.

Post-reaction contaminating molecules are converted into relatively harmless chemicals such as carbon dioxide and water. This is a classic example of oxidation and therefore certain air cleaners that work in this way sell the filtration as PCO technology (photocatalytic oxidation).

ACH VALUE

The ACH value indicates how often the air cleaner can exchange the air in a room with clean, fresh air every hour. In short, the number of purification cycles is that the purifier is completed within one hour. It is usually expressed in the multiples of “x”, for example: 3x, 4x, 6x, etc. The higher number means that the machine is more efficient at purifying air in the room. If you have an asthma patient at home, it is advisable to purchase an air cleaner with a rating of at least 6x.

There is also a reservation. ACH classification is directly linked to the maximum square foot surface that the air cleaner can handle. So if your purifier comes with a 5x rating and specified for 200 sq.m. Ft., This means that if you place the purifier in a room that is larger than 200 sq.m. Ft, this will not maintain the 5x exchange rate. The efficiency would go down and the air might not be that clean.

CADR

CADR stands for Clean Air Delivery Rate so this classification was developed by the Association of Home Appliance Manufacturers (AHAM) and helps consumers know how well the air purifier can clean the air in a certain room. As a result, not all air-cleaning devices have a CADR classification in their specifications list. Only manufacturers who have independently registered for the AHAM test .

The most important advantage of the CADR classification is that you can measure how large the air cleaner can process smoothly. But unfortunately, the market for air purifiers in India is not well regulated and new and unknown manufacturers can state a maximum rating of square meters for their purifiers that may or may not be 100% accurate.

The CADR assessment measures three types of air pollution:

  • Dust
  • Tobacco smoke
  • Pollen

The measurement for each category can vary between 10-450. A CADR classification can be, for example, 200/210/180, with 200 referring to dust, 210 to tobacco smoke and 180 to pollen. The higher the number, the better the air treatment against that pollution. So if you are confused between two or more models with the same square meter rating, you can use the CADR rating as the decision maker.

Weight, portability and noise

Air purifiers are heavy devices of a few kilos. If you plan to use one air cleaner for multiple rooms, we strongly recommended that you choose the lightweight model. It is also good to have a treatment plant with castors for better portability.

If you want to use the air purifier in the bedroom at night, noise emission levels of the device would become crucial. Air cleaners with ionization technology or UV technology usually do not come with a fan and are therefore extremely quiet. So make sure your air cleaner has that setting so that you can keep the fan speed to a minimum to reduce the noise level.

Maintenance and operating costs

Air cleaner requires a lot of maintenance so their filters must be clean regularly, usually by disconnecting the exterior and wiping with the wet cloth. Air cleaners with a HEPA filter or carbon filter require routine filter changes that can be expensive. It is therefore advisable to know the costs for filter replacement before selecting the model. This type of filter retains pollutants and eventually gets clogged.

If they are overlooked, they can be completely suffocated with trapped particles and cannot purify the air further if they are not replaced. Ionic air purifiers are the cheapest device to buy and maintain compared to those with HEPA filters. They do not have to be replaced for very long.

Although air purifiers may seem fairly economical at first glance, if you want to use them all day long, the power is relevant. The higher the power, the more energy it would use, leading to heavy electricity bills. Portable home cleaners generally have a wattage of around 50-70W. But there are few premium brands that offer a purification installation with a wattage of 20 W or lower. If you plan to use air cleaner continuously for a longer horizon, do not miss the wattage of the device.

Placement of air cleaner

Air purifiers that use ionic / UV filtration technology do not work with the help of a fan, but rather emit ions and radiation in a circle of 360 degrees. If you place the device close to the wall, the total output . The best placement for such purifiers is in the middle of a room. And in the event that placing an air cleaner in the middle of the room is not feasible for you, it is best to avoid ionic / UV based air cleaners. In addition, as we mentioned earlier, ionic air purifiers release ozone, which can lead to problems for asthmatics.

The air purifiers with HEPA filter rely on a fan to draw dirty air into the machine and push clean air back into the room so placing the machine under a table, behind the couch, against a wall or in a place that blocks this airflow will hamper performance. The good thing is even if they are not placed in the middle, but at least 2-3 feet from the wall, these cleaners can work smoothly.
