Things to Consider While Purchasing an Air Purifier

To choose an air purifier, you need to consider several factors like room size, power consumption, noise levels and finally the cost. We have tested on many and checked the performance by switching to low-high speed variations.

Given below are the factors responsible for the better performance of air purifier. Check them in detail.

1. Types of filters used in air purifiers

Different air purifiers types target different pollutants, so it is important to identify the pollutants that you want to eliminate from the room and enjoy the fresh air. For your convenience, we have provided different types of filters used in purifiers. Let’s have a glance at the Top 5 air filters for home that are very popular now. (2)

(a) HEPA filter(3)

HEPA is the acronym of High-efficiency particulate air. This HEPA filter has major application in homes, offices, automobiles, air crafts, and hospitals to remove impurities present in the air.

It satisfies the standards set by the DOE- Department of Energy. To qualify, it should filter out 99.7% of PM 2.5 particles.

The best HEPA air filter in India is typically made with fiberglass material and the pollutants, particles can easily pass through it and the working can be explained using 3 mechanisms namely- interception, impaction, and diffusion.

Large contaminants get trapped when they pass through the fiber layer via interception mechanism. Medium-sized particles move through the filter via impaction and diffusion mechanism for small pollutants. All of them bump into the fiber layer and set-up on it.

Pros

  • Improves health.
  • Best cheap air filter.
  • Removes 99% of PM 2.5.
  • Produces fresh and clean air at indoors.
  • Can be used as high-efficiency furnace filters.

Cons

  • Cannot handle smoke and odors.
  • Incapable of trapping small particles.
  • Microbes stick to HEPA filter can reproduce, resulting in more number.

(b) Activated carbon filter

Activated carbon or charcoal is processed to have a small volume of pores that helps to increase the surface area available for any sort of chemical reactions. 1 gram of activated carbon contains 3000Sq.m of surface area.

The properties of activated carbon like high chemical bonding and absorbent ability will make the device more efficient for capturing harmful pollutants like gases, smoke, and odors. Once the carbon filter traps all the particles, they cannot release back into the air thereby eliminating particles completely.

For those, who are willing to have high-end air purifiers in Delhi that completely deter the odor, smoke, and VOC (volatile organic compounds) then it’s preferred to use an activated carbon filter.

Pros

  • Most absorbent filter.
  • Robust design.
  • Easy to maintain.
  • Best budget air purifier filter.
  • Filters fumes, smoke, gases and odors.
  • Will not release pollutants back into the atmosphere.

Cons

  • Shorter lifespan.
  • Not effective against bacteria and viruses.

(c) UV technology

Implementing UV technology in air purifiers is an excellent method to kill harmful bacteria, and viruses.

When you install it in purifiers, the microorganisms passed through the UV rays are no longer existed.  Its primary function is to kill only the bacteria, viruses, yeasts, and molds. But cannot handle the dust, smoke or allergens in the air. To attain greater performance, it is associated with other filters where it cannot do specific operations.

When you purchase the UV air purifier, make sure the system does not produce ozone (high-concentration).

Pros

  • Easy to clean and install.
  • Best air filter for home.
  • Reduces unpleasant odors in a kitchen.
  • Focuses on eliminating microscopic elements.

Cons

  • Expensive filter.
  • Do not kill the harmful particles present in the air.

(d) Negative Ion

Negative ion is a system that uses high voltage to ionize or charge the air molecules. It is a high-end air purification process that is fabricated around ion generators.

The working operation of the device is such that it drives the stream of negative ions that attract dust particles and allergens in the air. As the majority of atoms are positively charged, they are attracted to the surfaces, walls and floors.

Some of the particles are being trapped by ionizers containing a metal plate and they need to be washed very frequently to perform the tasks effectively.

The major advantage of using ionizer filter is that it removes ultra-fine particles up to 1 micron without using fans or motors.

Pros

  • Helps to promote deep sleep.
  • Very inexpensive filter.
  • No use of fans or motors.
  • Removes the elements up to 0.01 microns.

Cons

  • Doesn’t remove odors.
  • Harmful to asthma patients.
  • Releases ozone into the air.

(e) Ozone

Ozone filters are designed to protect from all kinds of toxins in the air unless the concentrations are higher than the people health standards. Its functionality is similar to the ionizer, but it alters the oxygen molecules and turns to ozone. It is very good at deodorizing and disinfecting the air.

As there are many popular brand ozone purifiers, all of them vary in the production of ozone.  Ozone cannot purify the air and is considered as the toxic gas due to the unstable molecules which are responsible for causing breath-related problems.

If you are an asthma patient or prone to breathing issues, then strictly avoid using ozone purifiers at home. For such people, it is recommended to use HEPA filters or Ozone-free air purifiers in India.

Pros

  • Eliminates toxins at high concentration levels.

Cons

  • Do not remove particulates.
  • Ozone is unstable and potentially a toxic gas.

To increase the lifespan of any air purifier, you need to change the filter very frequently say- once in every 2-3 months. It, in turn, protects you from inhaling poisonous gases and keeps you healthy all the time.

2. CADR- Higher the CADR better the Air Purifier

CADR abbreviated as Clean Air Delivery Rate. It is actually a performance indicator to determine the efficiency of an air purifier. Most people often get confused with the terminologies like airflow rate, filters, and CADR air purifiers. Here is what exactly the CADR rate is all about.

What is CADR?

CADR rate defines the maximum amount of clean air offered by an air purifier. In other words, it can be expressed as how well the purifier can reduce the allergens, pollutants, and chemicals in a room. Higher the contaminants, faster it purifies the air.

The tests of CADR are being carried out by AHAM-Association of Home Appliances Manufacturers to analyze the performance of a purifier with respect to dust, pollen, and tobacco. Initially, the purifier is kept in a small/medium sized room and CADR rate, the percentage of impurities are determined in just a time gap of 10-20 minutes.

 Given below table completely explains the CADR ratings of different impurities present in a room.

Impurities CADR Rating (Microns)
Pollen5 – 11
Dust0.5 – 3
Tobacco smoke0.10 – 1

To be more specific, higher CADR air purifier filters very quickly than the lower ones. In case, if both the purifiers have the same CADR-rating then purifying performance will be the same.

ACR- Air Change Rate

Air change rate is a key factor for controlling indoor air-pollutants. It is defined as the volume of fresh air needed in a room by measuring the number of persons and size irrespective of indoor airborne chemicals.

Higher the ACR, the higher air flow and energy consumption and vice-versa. It is recommended to have purifier with 250-700 ACR which is too good in a bedroom to breathe fresh air.

To calculate the room air changes, measure the airflow in a room and multiply with 60 minutes per hour. And then divide with the volume of the room in cubic feet.

ACH =   60*Quantity/Volume

An electrostatic precipitator is a device used to filter out the particles like dust and smoke. They are actually designed to recover the valuable industrial materials that are used for pollution control at industries and power generating stations.

Its functionality is similar to the Ion and ozone generators. Yet, the particle is collected on a metal plate and can be cleaned for further usage.

As we know that air purifier is useful in deterring the toxins present in the indoor air. We mostly prefer to buy the popular brand air purifiers in India like Honeywell, Philips, Atlanta, Avizo, Ooze, Sharp purifiers etc.
Of all, Honeywell and Philips air purifiers rank top due to amazing features that help to improve the indoor air quality. But still, it’s tough to decide the best among both purifiers as they offer equal performance in cleaning the bad air.

The Honeywell air purifier has washable filters along with smart features like child lock, fan speed, sleep mode, indicators to completely eliminate the PM 2.5, dust particles and allergens. Whereas Philips air purifier is a budget-friendly device that uses Nano-protect filters+ sensing technology, to first sense the contaminants present in the room and then starts purifying the air.
