Thus the purpose of this long post to guide you on what air purifier is, what it does and how you can benefit from getting one for yourself and family.

Kindly forgive me for making this post, along one indeed but this is exactly what you need to before acquiring one of the air purifiers out there. But feel free to jump to any section that’s important to you with a table of contents.

What Is Air Purifier?

Air Purifier, is known as air cleaner is a device that removes contaminants from the air in the room to improve indoor air quality. It is most beneficial to people suffering from allergens and asthma.

Air purifiers also help in eliminating second-hand tobacco smoke.  Aside from using an air purifier at home or offices, they can also be used in the industries to remove impurities from the air before processing.

What Does Air Purifiers Do? (Uses)

Air purifier helps to capture air pollutant that contaminates the indoor air quality you inhale into your lungs like pet dander, pollen, dust mite VOCs, gases, ash, tobacco smoke, unpleasant odors, etc. that may cause you and your household ill health.

By removing particles from the air, these contaminants don’t have the opportunity to get inside your lungs as you breathe. The less bad particles you inhale, the healthier you stay.

How Do Air Purifiers Work?

The air purifier does a good cleaning job by sucking in all the poor quality indoor air into the air purifier, then this dirty air is made to pass through various filters incorporated in the air purifier, which after the purification of air inside the air filters, the purified air is pumped out into the room.

The air purifier keeps repeating these processes to keep the indoor air clean and well-circulated in the room.

Of which when the filter is oversaturated with this air pollutant, you either remove the filters and replace them with new one or you vacuum them and replace them back. But it all depends on the brand you purchased.

Let’s look at various stages air purification goes through before coming out clean:

How do air purifiers work?

Stage 1: Pre Filter

This is the first stage of all air purifiers no matter the type you bought. As soon as the air purifier encounters contaminated air in the room as its first line of defense it captures bigger particles like dust, animal hair, mold, pollen, dust mites from the polluted air.

It also reduces the pressure on the filters behind, thus increasing their efficiency.

Stage 2: Customize Filter

At this second stage, the purifier captures and cleans the air of yellow dust, NOx, pollen, SOx, bacteria, pet allergens, exhaust fumes, mold, Influenza, legionella, and VOCs. It is called filters of different needs.

Stage 3: Deodorization Filter

Air purifier manufacturers have actually conquered the warning Environmental Agencies to consumers that air purifiers are not effective at capturing gases and volatile organic compounds by making air purifiers with deodorized filter.

This filter traps and cleans the air of gases and VOCs, Noxious gas, the smell of foods, the smell of animals, the smell of cigarettes, H2S and odors.

Stage 4: HEPA Filter

HEPA filter is the core technology of air of all air purifiers. They are the best powerful filters made form minuscule glass fibers.

These fibers are then tightly woven to trap 99.97% of the air pollutants with size of 0.3microns or more. As many times as the air passes HEPA filters, the cleaner the air becomes.

HEPA filters clean the air of particles such as mold, pet dander, fine dust, cigarette fumes, dust particles, dust mites, smoke, pollen and allergies.

Stage 5: Activated Carbon Filter

The main work of this particular filter is trap and eliminate odors, formaldehyde, chemicals, smoke, VOCs, cooking odors, household odors, tobacco smoke, etc.

These are the five stages of air purification passes through before coming out cleaner but note that not all air purifiers in the market have these five stages, No. Some air purifiers are three-stage filters, some are four stage filters while some are five stage filters depending on the type and work it meant to do.

Bottom line: The effectiveness of your air purifier depends on the number and types of type of filters it is constructed with. The basic air purifier in the market has 3stages filter, which are pre filter, True HEPA (HEPA Type or HEPA like) and activated carbon filter.

Heads up!

Air Purifiers labeled HEPA type or HEPA like are not as effective as True HEPA filters. Bear this in mind.

Why Do You Need Air Purifier?

There are so many reasons why you need at least one air purifier in your home. Let’s look at these statistics:

  • Indoor air pollution is the 8th most important risk factor for diseases and is responsible for an estimated 2.7% of the global burden of all diseases.
  • Between 1.5million and 2million deaths a year could be linked to indoor air pollution
  • Around 50% of the world population (about 3 billion people) is exposed to indoor air pollution from open fires and wood-burning cooking stoves.
  • In the USA, between 2,100 and 2,900 cases of lung cancer in non-smokers are linked to radon exposure.

Things To Consider While Buying Air Purifier

1. Room Size

Buy air purifiers that are designed to operate in a space that is 20 to 40% larger than your room for optimal performance.

For example, if your room size is 224sq.ft then you should buy an air purifier, which has 20% to 40% more coverage area of 300sq.ft.

2. Filtration System

Buy air purifiers with True HEPA filter and Carbon filter. They are good at capturing about 99.97% air pollutants measuring 0.3microns diameter like dust, dander, pollen, mold and other common allergies at home while Activated carbon filter unpleasant odors and harmful gases.

But in case you are on a tight budget, you buy an air purifier with either one of the filters depending on your need but you will not get a satisfactory performance. Get HEPA filter air purifier if you want only clean air or buy a carbon filter air purifier if you have specific allergies.

3. Cleaning Air Delivery Rate (CADR)

This is a rating that shows how faster and air purifier can clean the air. The higher the number of CADR the better and faster it cleans the air. Buy air purifiers with 300 and above number of CADR.

4. Know Your Budget and Needs?

Customers are advised to get an air purifier that has True HEPA filter and carbon filter for maximum performance though it may be costly but it worth it to give you value for money. However when in a tight budget, you can purchase as follows:

  • If you need odor, gas and allergies elimination – buy True HEPA filter with carbon odor elimination filter. This type can remove pet dander, odor, hair, ragweed pollen, grass pollen, household dust, mold spores, dust mites debris, tree pollen and smoke out of the air.
  • If your need is to remove dust and general cleaner air – buy HEPA type filtration electrostatic/ collector plates air purifier. This can remove pet dander, odor, smoke and household dust.
  • If your need is to remove and eliminate bacteria and other germs –  buy air purifier with UGVI technology.  It removes bacteria, viruses, and germs out of the air you’re breathing.

5. Cost Of Replacement Filter

Buying an air purifier requires a maintenance cost because the initial cost of purchase is not only the money you will spend. For you to get the best out of your air purifier, HEPA filter requires you changing them every 6  to 12 months depending on the brand you have and carbon filter requires you to change them every 3 months.

But some air purifiers do not need a filter replace rather you vacuum them and replace them back. So if yours requires replacement, be ready for it. Air purifier replacement can cost within $12 to $200.

6. Energy Cost

It is very necessary that you understand the monthly energy consumption your air new acquired air purifier to ensure that you will be able to foot the bill. This is how to calculate the monthly energy cost of your air purifier.

7. Certification

Look for air purifiers with Energy Star Certification, it simply means that they energy certified and can run around the clock efficient consuming little electricity. Energy Star certified purifiers are 40% more energy-efficient than standard models.

Secondly, look out AHAM Verified Seal. AHAM stands for the Association of Home Appliance Manufacturers Certification program. They provide Clean Air Delivery Rate (CADR) and room size guideline on the seal and was approved.

8. Noise

The air purifier should not be too noisy. Most of them are too noisy when set on the highest. So you can buy one that is large than your room, they are effective when you run them on low and there will be no noise.

Better still. Whichever you buy, you can set to run them on high when not around and run them on low when you’re in.

Some Terminologies To Keep In Mind

1. CADR (Clean Air Delivery Rate)

It means how efficient an air purifier can clean a room. A CADR of 300/hour means that the air purifier can clean all particles in 300m3 in an hour. Note that the high the CADR number, the better the air more it filters per hour for that particle size.

If your challenge is smoke, choose the air purifier that has CADR for smoke and vise visa.

2. CFM (Cubic Feet Per Minute)

It gives you information on the efficiency of the air purifier. Example 200 CFM means the purifier can remove 200 cubic feet of air per minute.

3. ACH (Air Change Per Hour)

This rating tells you how many times the air purifier can exchange the air within a room with clean, fresh air every hour. The higher the number, the more efficient the device is at purifying the air inside a room.

4. Energy Star

The rating certifies that this device is energy efficient.

5. AHAM (Association of Home Appliances)

The rating means that the particular has been to clean up to the square feet area mention by the manufacturer and the devices is effective at the job it was built for.

What Does It Cost To Run An Air Purifier?

Air Purifier is related differently depending on their sizes and square feet area of coverage. So before you buy check out the descriptive section to know the wattage of the purifier, you’re buying. The higher the wattage of the air purifier, the higher the energy cost.

How To Calculate An Air Purifier Energy Cost?

Before you do this calculation, find out the rate of electric charge per kilowatt-hour of your state so as to get the real cost because it differs from state to state. For the sake of this article, we will assume 0.80 cents to be our electricity charge per kWh.

  • Know the wattage of air purifier you want to buy.
  • Know the number of hours you want to run it.
  • Calculate the total wattage consumption per day.
  • Convert total watts to electricity measurement.
  • Calculate the monthly usage by multiplying the total kilowatt per hour by 30 days to get the monthly electricity kilowatts.
  • Finally, use your local electricity rates to multiply the answer. There you have your monthly energy cost of air purifier.

Example:

Assumed air purifier wattage = 70w

Assumed running hour = 24hrs

Assumed cost per month = 0.80 cents

Formula: Watt (W) x Hour (hr) x Number of days x daily electricity rates = Cost of air purifier per month.

70w x 24hrs = 1680w

1680/1000 = 1.680kilowatts

1.680 x 30(days) = 50.4KWh per month.

50.4KWh x 0.80 cents = $42.32

That means the cost of your air purifier energy bill per month is $40.32

If you’re running yours for 12hours, divide your total cost per month by 2.

E.g. 40.32/2 = $20.16

To get air purifier energy cost per year, multiply the total monthly cost by 12.

E.g. $40.32 x 12 = $483.84

What Are Air Purifier Purifying Techniques?

As long as air purification remains, there are only two ways indoor air can be purified, which are Passive and Active purification techniques.

Passive air purifiers are more efficient than active air purifiers. Reason being that they remove all dust and particulate matter permanently from the air and collected in the filter. And the most common types of air purifiers under this category are High Efficient Particulate Air (HEPA) filter, Activated carbon filter and Ultraviolet Germicidal Irradiation (UVGI) filter.

Whereas Active air purifiers release negatively charged ions into the air, causing pollutants to stick to surfaces, which can redistributed into the air, causing health problems. Such air purifier type is the Ionizer air purifier.

Types of Air Purifiers

#1. HEPA Filter

This is the #1 efficient air purifier, which has been certified to remove up to 99.97% of 0.3microns particle and are usually effective at removing large particles. They’re healthy to be used indoors because they do not generate ozone and harmful byproducts that may affect the human body system at course operation.

In addition, kindly know that some air purifier that is labeled HEPA type or HEPA like has not been certified to meet up with the requirement of HEPA. When buying, buy the ones that are labeled True HEPA filter if you need efficiency.

#2. Carbon Filter

These are porous materials that can adsorb volatile chemicals on a molecular basis but do not remove larger particles. They work efficiently by changing contaminants from a gaseous phase to a solid phase. Activated carbon filters are normally used in conjunction with True HEPA filters to eliminate dust, particulate matters and gases/odors from the air.

#3 UVGI Filter

Air purifiers with UVGI light are good at removing harmful pollutants like bacteria, virus and fungal spores. They are mostly used in hospitals to disinfect the laboratories and patient rooms.

Other types not really recommended to you if you have breathing related problems.

#4 Ionizer Filter

They emit negative ions in the air that attract all the positive charge particles like dust and makes them heavy to fall on the ground or surfaces. They also generate ozone and other oxidants as a byproduct of the course operation in order words they are good for your health.

#5. Ozone Generators

These devices produce ozone, a molecule that can react with certain pollutants to alter their chemical composition. This may result in dangerous indoor air quality.

According to consumer report, studies done by EPA had shown Ozone has been linked to decrease in lung function and increased risk of throat irritation, coughing, chest pain, and lung tissue inflammation. From their test, it was discovered that most air purifier brands in the market contain more than 0.05 parts per million, which is the healthy amount recommended by the FDA.

What Should I Look For When Buying Air Purifiers?

You should look for these features listed below when buying your air purifiers.

Good Features

  1. An air purifier with washable pre-filters. They collect large particles before reaching the main filters. Which are HEPA and Carbon filters, thus extending its life span and saving you a few dollars on filters
  2. Air purifiers that have filter replacement indicator light. The flashing out of the light when the filter is oversaturated with pollutants will reduce you the stress of suffering under a clogged air purifier that will never.
  3. Air quality sensor – it helps to detect how polluted the air is and automatically adjust the air purifiers cleaning speed accordingly.
  4. Carrying Handle and Wheels – this will enable you to move them from one room to another room no matter how many pounds it weighs.
  5. Remote control or Phone app. This is to let you adjust the settings wherever you’re.

Bad Features To Avoid

  1. Any air purifier that will emit ozone at the course of operation.

How To Get The Best Out Of Your Air Purifier?

  1. Replaced your odor (carbon) filter and HEPA filter when due. As the general rules imply, change HEPA filter every six to twelve months. And carbon (odor) filter every three months.
  2. Place it at the right stand. Due to some of these air purifies can be bulky. Place them in the room where you stay often. If you have multiple rooms you get one for each of the rooms.
  3. Run your air purifier 24/7. When not in the room set it on high and when inside set them on low to less noise.

Other Ways To Improve Your Air Quality Indoor Are:

1. On the days you’re not running your air purifiers, ensure to open your doors and windows for cross ventilation. If you have dust or pollen allergies that prevent you from doing that, you can run your air conditioner or forced-air cooling system with a clean air filter.

2. Quit smoking indoor, burning candles and wood fires.

3. Use an exhaust fan in the kitchen, bathroom and laundering room.

4. Ensure you vacuum regularly because there is no air purifier that will remove dust mites ad pet hair that settled on furniture and carpet unless they air distributed and redistributed into the air. Use vacuums that have HEPA filters, they are more efficient in cleaning carpets and furniture.
