One may live a week without water, two weeks without food but without air? One will die within minutes. But from time to time, we tend to forget about the importance of fresh air in our outdoors and indoors.
According to the research of Human Research Ethics Committee (HRECs), a person spends 15+ hours in a day in indoors, in both office & home. And it’s so unlikely to get pure and fresh air in both places. As a result, one may get sick gradually. So, the health experts highly recommend “take your breath at fresh air”.
Considering all the above-mentioned facts, modern science stepped up and provided us with air purifying technology which purifies the existing air.

What To Look When Choosing The Best Air Purifier
Some of the fundamental factors to consider when shopping for an air purifier include:
There are primarily two types of air purifiers: room air purifier and whole-house air purifier. The former is typically smaller and less expensive compared to the latter. According to Consumer Reports, a room-purifier is the right choice if your home does not have a forced-air heating/cooling system or if you are shopping for an air purifier that you can move from room to room.
On the other hand, a full-house air purifier is an ideal choice if your home has a forced-air heating system.
At this stage, it is worth mentioning that a sub-category of room air purifiers is called dedicated ozone generators that are designed to emit a tolerable amount of ozone.
However, the US Environmental Protection Agency (EPA) warns consumers to avoid such air purifiers because ozone can damage the lungs and worsen chronic respiratory diseases such as asthma when inhaled. Healthy people can also experience breathing problems after inhaling ozone.
Also, a research article published in the New England Journal of Medicine found that exposure to even low levels of ozone increases the risk of developing severe health conditions including pneumonia and chronic obstructive pulmonary disease.
2. Air filtration technology
Commercially available air purifiers vary widely depending on the type of air filtration technology deployed. Presently, HEPA technology is probably the most widely used technology in air purifiers. This technology was basically developed by the US Atomic Energy Commission to remove radioactive dust particles from the air.
HEPA filters are manufactured from finely woven glass particles that form a pleated surface area for trapping air pollutants larger than 0.3 microns. Although HEPA filters are highly effective, they are expensive because they require replacing after 12 to 18 months depending on usage.
The cost of a single HEPA filter ranges from $70 to $125. Moreover, the dense structure of HEPA filters means they are not as energy-efficient as other types of filters.
Besides HEPA technology, some air purifiers use Ultra Low Penetrating Air (ULPA) technology. Simply put, ULPA is a stricter version of HEPA air filtration technology that was developed for use in hospitals and “clean rooms” such as those found in the semiconductor manufacturing sector.
Another category of air purifiers uses activated carbon filters to remove air pollutants found in indoor environments. To achieve this goal, they rely on carbon treated with oxygen thereby opening millions of tiny pores that are ideal for absorbing/bonding with pollutant particles. Air purifiers that use charged media filters, in essence, rely on two technologies: an electrostatic charge generator and a particle filter.
Unlike air purifiers with HEPA filters, those with charged media filters can trap particles as small as 0.1 microns. The downside is accused media filters lose their efficiency quickly. Some manufacturers produce air purifiers that use antibacterial and germicidal filters, which are simply HEPA filters treated with chemical compounds that can kill harmful microorganisms such as bacteria.
Photocatalytic oxidation (PCO) is another type of air filtration technology that is based on a metal plate coated with titanium dioxide and uses UV light to break the chemical bonds that hold pollutant molecules together. Other types of conventional air filtration technologies include electrostatic precipitator, ion generator, photo plasma, polarized media electronic and titanium dioxide air filtration technology.
The size of an air purifier is calculated using the Clean Air Delivery Rate (CADR) metric, which was produced by the Association of Home Appliance Manufacturers (AHAM). In essence, CADR is a metric based on a number of cubic feet of air an air purifier can filter per minute. As such, a high CADR figure means a more efficient air purifier and vice versa. To calculate the CADR for a room, multiply its square footage by 0.75.
The features of an air purifier typically vary depending on the product size, model, and brand. Still, one of the most common and useful features is a fan for sucking in air. An article published by Consumer Reports states that air purifiers without fans tend to work poorly compared to purifiers with fans.
Another useful feature is a servicing indicator to alert you when it is time to replace essential parts such as the air filter. Other key features found in air purifiers include a dust sensor, UV-C sanitizer, filtering frequency controller, and air quality monitor. Fortunately, consumers can use product comparison sites to evaluate and compare air purifier features. This is in addition to comparing the prices of different air purifiers.

How Do Air Purifiers Work?
In general, air purifiers use fine sieves called air filters to trap and remove contaminants from the air. As such, air purifiers with denser sieves are generally more efficient because they are able to trap smaller pollutant particles.
Examples of indoor air pollutants include pathogens, bacteria, viruses, antigens, bad odors, toxins, irritants, and VOCs. With this in mind, the US Department of Energy (DOE) has set air purification benchmarks that manufacturers of air purifiers must meet.
For instance, air purifiers based on HEPA technology must remove at least 99.97% of air pollutants that are larger than 0.3 microns. A micron is a unit used to measure the size of air particles and it is equivalent to 1/25,400 of an inch. Other common air purifying technologies include Thermodynamic Sterilization (TSS) and Ultraviolet Germicidal Irradiation (UVGI).
Frequently Asked Questions Related to Air Purifier
1. Do home air purifiers work?
Technically speaking, this is quite a subjective matter. Most home air purifiers are used for active filtration. As far as trapping dust particles and pollen are involved, home air purifiers work best. However, if you’re looking to capture other organic compounds, then a simple air purifier won’t do the job.
2. Are HEPA air purifiers worth it?
Yes. HEPA air purifiers are worth it if you’re looking for protection from harmful dust molecules and particles. The main reason HEPA filters are warranted such respect is due to their excellent filtration rate. HEPA filters can capture 99.97% of all particles that it interacts with, which may even be as small as 0.3 microns.
3. Do air purifiers make your house smell better?
Generally speaking, an air purifier might not make your house automatically smell better. For that, you might require a particular home air purifier that utilizes an Activated Carbon filter. Since most purifiers lack this feature, they only serve to clean the air as opposed to making it smell better as well.
4. How long does it take an air purifier to clean a room?
Several factors work in conjunction when it comes to cleaning a room. These include the speed of the fan unit, the size of the room, and the purifier’s coverage. Either way, it is speculated that the standard purifier would take anywhere between 30 minutes and 2 hours.
5. Is it OK to leave air purifier on all night?
Yes. There are no safety precautions to worry about as far as an air purifier is concerned. The main issue that some individuals have is related to the electricity bill that this might generate. If you’re looking to balance things out, you can slow down the overhead fan a little.
6. Where is the best place to put an air purifier?
There are several platforms available where you can get good air purifiers at decent rates. However, it’s best to refer to online stores that can give you access to a wide variety of models with the latest feature. However, make sure that the online store has a return policy, lest you aren’t pleased with the product.
7. Should an air purifier run all the time?
This depends entirely on you. If you’re in the house at all times, then it’s fine to use the air purifier operating 24/7. However, if you’re not home, then it’s reasonable to argue that you only want it operating when you’re at the house. In the end, this is dependent entirely on you and based on how you like things around the house.
8. Do air purifiers improve sleep?
There have been several studies done on this matter; all of them came to the same conclusion. Air purifiers have been noted to improve the quality of sleep. This is credited mostly because air purifiers create the perfect environment in which an individual can rest, especially an environment that is free of dust, pollen, allergens, dust mites, pet dander, etc.
9. Which is better air purifier or humidifier?
Technically speaking, none is better than the other. If you’re looking for an optimal living environment, then it’s best to use both of them side by side. An air purifier would work to make sure that there isn’t any dust in the immediate vicinity. A humidifier, in conjunction with that, ensures that there is ample moisture in the room.
10. How long does an air purifier last?
In theory, air purifiers are supposed to last about five years easily. However, if you’re a realist, then it is best to assume that your air purifier will give you 2-3 years top. This number is also dependent on factors such as usage, particle matter in the air, and room size.
11. Do air purifiers use a lot of electricity?
All air purifiers consume varying amounts of activity. Generally speaking. However, it isn’t as much as people would argue. HEPA air filters utilize about 50-200 watts of electricity. If you’re looking for perspective, a computer uses 365 watts.
12. Will an air purifier help with dust?
Yes. An air purifier would help with getting rid of unnecessary dust in the house. However, this doesn’t mean that it will capture all of it. Some dust, especially those in tight spots, will remain there.
13. Why does my house get so dusty?
The house can get dusty due to a plethora of reasons. The main one can be attributed to open windows. As air blows in, it carries dust particles with it. The second reason is the dust that sticks to our shoes and clothes that we carry inside when we enter the house. Lastly, it can be said that dust accumulates quite quickly. If it isn’t being cleaned as fast as it is being accumulated, then the house will get dustier with time.
14. How do you get rid of dust floating in the air?
The best way to get rid of floating dust is by using a HEPA air filter. The main reason for this is due to the filtering ability it offers, which guarantees a capture rate of more than 99% and reputed with being able to capture particles as small as 0.3 microns. Furthermore, it makes sure that you use the air filter continuously for some time without any major pause.
Some of the essential considerations when shopping for an air purifier include the air filtration technology, size, type, and features.
Most of the air purifiers in the recent market today use High-Efficiency Particulate Air (HEPA), Ultra Low Penetrating Air (ULPA), activated carbon filter, charged media filter, antibacterial and germicidal filter, photocatalytic oxidation, ion generator, ozone generator, electrostatic precipitator, and titanium dioxide air filtration technology. Each has its fine share of merits and demerits.
However, you should avoid air filters that use ozone generator filters because they tend to increase the risk of developing respiratory diseases.
Hopefully, this article will help you find effective, cost-saving, safe air purifiers, just like you want.
