Air Conditioners And Air Purifier Filters

Air Conditioners And Air Purifier Filters are paramount components in an air purifier or air-conditioner. It withdraws dust particles from the air. It is necessary and essential for the functioning of the Air purifier air conditioner.

If you are planning on buying the Best Air Purifiers in India, you must look out for many things before you actually decide the one.

The dust and the remains/residues on the filter will occlude the passage of air. This hinders the cooling and decreases efficiency. This will also influence the electricity bill.

You can protect yourself from this disproportionate expenditure by merely cleansing the air filter. If needed one can opt for a further filter.

However, it is always better to keep changing the filters after every 5 to 6 months. But, it also depends on the usage by the user. The topmost important, as well as crucial thing here, is to make sure that dust is not accumulating on the filters.

There is a tremendous rise in indoor air pollution since the early 1990s. On average we expend 80% of the moment indoors; the possibilities of inhaling pollution are more elevated.

Types Of Air Purifier Filters and Air-conditioner Filters

1. PM 2.5 Filter:

ac pm 2.5 filter

You cannot control the pollution levels outdoors as it involves various factors as well as indoor air. PM 2.5 Filter is specially designed to trap the microparticles from the air. It is necessary to purify the indoor air that we breathe. So you can install AC units having PM 2.5 filters and improve the quality of the indoor air.

This filter is consists of a polytetrafluoroethylene(PTFE) membrane which reduces friction. This membrane filter is applicable in gauging air quality through the EPA test method and can trap the microparticles effectively.

Positive
  • It is so useful as it removes the minutest of pollutants
  • It will cost less compared to the HEPA filter.
  • It is an essential constituent of the modern-day AC.
Negatives
  • It cannot trap impurities less than 2.5 microns in diameter

2. Fiberglass Air Filter:

Pleated air filters will be a cost-effective and efficient option, as they are able to trap smaller airborne particles than fiberglass filters. When it comes to pleated filters, the more pleats the better.

Positive
  • These air filters come with higher MERV ratings so they’re much more efficient in removing smaller particles from the air.
  • Along with doing a better job of cleaning the air, they’re still pretty inexpensive.
  • Environmental friendly.
  • Disposable pleated filters are a great choice for those who aren’t particularly sensitive to atmospheric pollutants but still want to maintain a clean environment.
Negatives
  • The filter is prone to having dirt build upon them, so you need first to make sure to get the right furnace filter size and second, replace them at regular intervals to ensure that your unit is working as well as possible.
  • This filter also restricts the airflow to your HVAC system, so you have to select the correct MERV rating otherwise your system could be damaged.

4. Electrostatic Air Filter:

Well, Electrostatic filters, also recognized as washable filters or reusable filters, are positioned on a furnace and typically perceive the position of a folded filter. The special electrostatic energized bits drive the dusty scraps towards the receiver, ambushing the dirty shreds within. These Air Purifier Filters are very much popular.

Well, I am sure that by this time, you must understand the adverse effect of pollution on indoor air. Moreover, it is more hazardous than the air possible out-of-doors. You have a variation in the quality of contaminants inside the apartment that you would never find outside.

These filters cost a little more but are also more efficient to keep the air clean. Electrostatic filters use self-charging fibers that attract and trap airborne particles with static electricity.

Positive
  • It catches a lot of small particles in the air, which makes them well-suited for households.
  • It is also designed to catch smoke particles, so they’re recommended for those who smoke indoors.
  • It also comes with a high MERV rating.
Negatives
  • This filter can be more costly to replace. If you end up experiencing the need to repair or replace them, you’re going to be spending quite a bit. For example, some units will need custom-sized filters, and these will be a lot more expensive. 

5. High-Efficiency Air Filters:

If you have pets in the house or anyone in your family has allergies or asthma, a high-efficiency filter is perfect for you. They are by far the most efficient at trapping particles and keeping your air clean and healthy. Keep in mind, however, that some high-efficiency filters may be so good at trapping particles that they actually restrict airflow. Consult an AC professional before purchasing a high-efficiency filter to make sure it won’t damage your system.

Positive
  • This filter is able to catch minuscule air-borne particles and remove them from the atmosphere.
  • It maximizes the cleanliness of the environment.
  • It has a higher MERV rating of at least 13, so the filter is to be used to prevent the spread of illnesses, and it is recommended to those with health problems such as respiratory issues.
Negatives
  • The filter is very thick because it is designed to remove so many pollutants from the atmosphere and so they can only be installed in certain homes.
  • Due to the high quality of the filter, it’s obvious that replacements and repairs will also add to the costs of maintaining it, that’s why it is not recommended for households without the health needs of optimal air cleanliness.

6. HEPA Filter:

The technology for this air filter was developed originally during WWII for removing the dust particles that were radioactive from the air to protect the respiratory systems of soldiers.

HEPA is described as a filter that apprehends 99.97 per cent of bits or particles dropping to 0.3 microns. It is tested using a standard by an association named IEST.

HEPA Air Filter_

When someone inhales air contaminants, the natural defense of the human body is a lot more vulnerable to particles under 0.5 microns. That’s the reason why these types of filters are recommended by doctors and allergists – they can remove most air contaminants even when they are extremely tiny.

The HEPA filter can remove all contaminants above since they’re bigger than 0.3 microns. These filters can’t capture fumes, cigarette smoke, and chemicals because they have smaller microns than 0.3. That’s the reason that you want to buy this type of filter that has a carbon filter that’s activated so that they are able to capture the allergens that the filter can’t.

Positive
  • Can remove allergens such as dust, dust mites, mold spores, and pollen, bacteria
  • The captured solid particles aren’t released back into your air.
Negatives
  • Is not able to remove odors, cigarette smoke, or chemical fumes.
  • Is not much effective when capturing tiny viruses
  • The microorganisms that the filter captures are able to reproduce or breed, which means that there are more populations of microorganisms.

7. Activated Carbon Filter:

Activated Carbon Filter is an example of many methods ordinarily worked in water treatment to eliminate contaminants before-mentioned as organic elements, and considering it also can liquidate odor-causing contaminants, it’s oftentimes used to make drinking water more appetizing and safe to consume.

activated carbon filter

This filter has little absorbent pores in them that react chemically to the pollutants as they’re going through it. This is what causes pollutants and carbon to bond so that they are trapped. This filter is good at clearing odors, chemicals, smoke, and gases from the air.

Positive
  • They absorb the best of all filters.
  • Capture gases, odors, cigarette smoke, and chemical fumes
  • Don’t release the contaminants into the air again
Negatives
  • Can’t remove microorganisms.
  • Can’t remove allergens such as dust.

8. Ionic Filter:

This filter is built around negative ion generators. It sends out a negative ion stream that will attract positive airborne allergen and dust particles. Because of this, the particles will become really heavy and will fall onto the ground. As most room surfaces tend to be positively charged, those particles are also attracted to those surfaces. That means the spots around this type of filter will get some dark spots on the nearby floors and walls. There are some ionizers that have electrostatic precipitators. These trap the particles on metal plates. To keep their effectiveness, it’s essential that the plates are regularly cleaned.

Positive
  • Can remove so many tiny particles that are as little as just 0.01 microns.
  • Can sterilize viruses, smoke, bacteria, and other kinds of toxic fumes.
  • It remains quiet when running because there aren’t any motors or fans.
Negatives
  • It can remove particles from the air but doesn’t remove them from a room. *Particles will land on the walls, furniture, and floor. They also may go back into the air.
  • It produces ozone as its by-product.

9. Ultraviolet Light Filter:

This filter uses UV light with electromagnetic radiation. This destroys pathogens such as bacteria by ending up the pathogens’ molecular bonds within the DNA. This filter kills the particles without any type of filtration.

This filter will work well for killing molds, viruses, yeasts, and bacteria which could be floating around in your air.

The best performance happens when these types of air filters are used with other kinds. This way they are able to work with one another so that a lot more air contaminant types are removed, like allergens, chemical fumes, and odor which this type of filter can’t remove.

Positive
  • Can destroy microorganisms like mold, bacteria, germs, etc
  • It helps by preventing disease and illness.
Negatives
  • Can’t remove the vast part of dust, solids, or allergens from the air.
  • Can’t remove gases, cigarette smoke, or chemical fumes.

10. Nano Silver Filter 

Nano Silver Filter, also known as Nano Silver Activated Carbon Filter is produced by actual coconut carbon, with fundamental impression to overcome Taste, Odor, Chlorine for pre-filtering persistence, and plus Bacteria defense struggled to UV Sterilizer but with cost conversion solution.

In a conventional way, the usual material used for the filtration of the air is Activated Carbon.

One should necessarily admit that activated carbon is great at eradicating contaminants from the air and water. Nevertheless, a lot depends on the microporosity and the exterior space. These Air Purifier Filters are very much popular.

Actually, there are different types of filters that are present in Air conditioners, or water purifiers, or air purifier. For example, the Catechin filterAnti- Bacterial FilterBaffle filterHepa filterAnti VOC filter, or the electrostatic filter.

Positive
  • Acts as a comprehensive counterpart to the activated carbon filters.
  • It can also assassinate other pollution-causing pollutants like pet dander, powder, and flakes.
  • Eradicates bacteria and other harmful elements from the air that the standard HEPA filters are powerless to do.
  • Utilizes less expanse.
Negatives
  • Excessive or Acute exposure to silver can cause the bacteria to become silver-resistant.
  • Silver has environmental interests and concerns, because of the poisonous influence it produces on different brands of cells.

11. Photocatalytic Filter

Photocatalytic filter

The photocatalytic filter is an excellent illustration where ultraviolet radiation or UV light serves as the superior element to cleanse the air of impurities with the assistance of a catalyst. This catalyst is known as Titanium dioxide.

Light has astounding endowments. It provides life to plants as they serve their own food using sunlight.

Not many bodies understand that light can also help in purifying the air we respire. Some of the most advanced air conditioners and air purifiers practice this aspect of light to disinfect and clarify the air.

Positive
  • Photocatalytic Filters do not ambush the pollutants in their purest form. Instead, they transform the dangerous organic contaminants into carbon dioxide and water.
  • The ultraviolet(UV) radiation has more exceeding energy than conventional light, and it is not apparent to the human eye.
Negatives
  • Ozone (O3), is one of the by-products of this reaction. Moreover, it is a dangerous air pollutant. It is a chemical modification of oxygen that can determine toxicity if breathed in massive quantities.
  • Disclosure to ultraviolet light, also known as Invisible light can proffer sunburn to your body as these light particles have more distinguished energy levels.

Merv Rating

It is the short word of Minimum Efficiency Reporting Value. This is a rating generally offered to air conditioners and refrigeration.

It can measure the effectiveness of air filters. The lowest MERV rating according to the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) is 6. The immaculate rating, which is also endurable, is 16.

The lowest Efficiency Reporting Value is reckoned according to the parameters mentioned below:

  • MERV 1-4 20% of large particles can be detected
  • 5-7 nearly 20-69 % of huge particles are detected
  • 8-10 can eradicate 85% of large particles and around 50% of tiny dust
  • 11-16 can eliminate more than 90% of big particles and 70 to 90 % of tiny particles
  • 17- 20 can sponge the most microscopic particles.
