Do Air Purifiers Actually Work? (The Truth About Air Purifiers)

The air inside your home can have levels of specific toxins up to 5 times more than the air outside of your home. Knowing this fact, we understand perfectly the need for something that can provide you with fresher air in the modern world. 

There’s no doubt that air purifiers are capable of cleaning a significant portion of air, wiping out all the dust coming in from outside, your pet’s hair, unpleasant smells and smoke. This is all very tempting, cleaning air like one would clean a carpet.

Despite the claims, are air purifiers a solid answer for disposing of indoor toxins? In short, they are to some extent. Keep on reading to get into the mechanics of how these machines work and if they’ll be a worthy addition to your personal space. Learn what to expect and look for in an air purifying device.

How do air purifiers work? 

Home air purifiers are on the rise to popularity, mainly as a response to the ever-worsening conditions of air and the increasing air pollution. Air purifiers, however, do not like up to the standards that their marketing sets and suggests.

Air purifiers typically have multiple filters for different purposes. One filter sucks in the air for purification, and the other flows out pure air outside.

The air takes a trip to the inside of the purifiers, toxic gasses and particles are caught through the filters. After this process, fresh air is forwarded outside. Ordinarily, filters are made of paper, fibre (frequently fibreglass) or lattice, and they require ordinary substitution to keep up with productivity.

As often as possible, it would be best if you change filters. For this, you need to check the purifier type and consider how many hours in a day you’ll use the device. 

Some filters are made so they can be used again and again after washing them out. However, they need to be looked after very consistently. You will not find reusable filters in good air purifiers.

You’ll likewise track down UV (bright light) filters available, which frequently guarantee to annihilate organic impurities like mould or microorganisms. However, many require higher wattage to be functional (also, a few microbes are UV-safe).

Filters aren’t the only functional mechanism of air purifiers. They also use ionisers. 



Ionisers attract negative ions from the air. The particles have resting dust around them that stick. Air purifiers use this mechanism to their advantage.

If you have your eyes set on an air purifier that ionisers’ cleaning mechanism, be warned of ozone. It’s a gas that, even in low amounts, irritates the throat and lungs. They can cause pain in your chest and make you go out of breath. 

This is a critical problem for people with lung disease and asthma. It would be helpful if you paid mind to buying a purifier with low degrees of ozone emission.

The good thing is that this information will be available on the package that air purifiers come in. It might also be said in advertisements.

Our suggestion, until extra testing and more strong industry norms are set up, is for individuals with units with plasma/ionisation to plug in their machines with those capacities off.

We insist on careful consideration of these things because there is the potential for unsafe results. You could also end up using up more electricity for a tiny improvement in air quality. 

The technology is new and not as developed as one would imagine, but the claims are significant. 


Are air purifiers worth the hype?

Also, the viability of air purifiers in actual circumstances probably won’t mirror those of controlled conditions in a lab (which is what those “almost 100% adequacy” claims are alluding to!). 

The area, stream rate, and run time for all will fluctuate, as will the conditions in the space. 

Different things happen at your home that might impact the viability, like ventilation (open or shut windows). New particles are continually arising, so the air probably won’t be pretty much as filtered as the cases might have you accept. 

Furthermore, to eliminate allergens, microbes or infections that have chosen surfaces, you want to use sanitiser cleaners as well as vacuums.

You might’ve heard about the claim that air purifiers can wipe out coronavirus. How much truth is there to that statement? 


Do air purifiers protect from Covid

Air purifiers that use HEPA filters can catch particulates the size of the Covid. In any case, the genuine adequacy at keeping somebody from getting the infection is as yet unclear, as the pace of transmission might be quicker than the air purifier can catch the particulates. 

Accordingly, we keep sticking to the CDC’s recommendation concerning best techniques for decreasing transmission hazard and staying away from openness to the infection as best as could be expected.


What should I look for in an air purifier?

What should I look for in an air purifier?

  • CADR (clean-air delivery rate): This is the cleaning velocity of the cleaner for eliminating smoke, residue and dust. Searching for a CADR of something like 300; over 350 is genuinely incredible. 
  • Size regulations: For legitimate adequacy, you want a model that will work for your room size. Pick a model intended for an area more extensive than the one you are equipping it for to perform it at a lower, quieter setting.
  • Authentic HEPA: Genuine HEPA filters are compelling at eliminating ultrafine particles (think: dust, dander, dust, mould and other everyday allergens in the home). The business standard is that the unit should have the option to eliminate essentially 99.97% of particulates, estimating 0.3-micron distance across in a lab setting. The genuine viability of these gadgets would be undeniably more minor as new contaminations are continually arising.

Author’s Note: There is no objective standard expression in the industry such as “HEPA-like” or “HEPA-type,” and these expressions are, for the most part, used as advertising ploys to get customers to buy the item.


Will an Air Purifier Benefit Me?

It’s critical to consider your home climate and the medical issue of individuals residing in your home. Ask yourself these questions before purchasing an air purifier:

  • Does anyone in your family or house suffer from asthma and allergies? 
  • Do you live in a metropolitan city or nearby a road with heavy traffic? 
  • Do you or someone in your home frequently catch infections? 


Features you should look for:

Features you should look for:

  • Auto mode: The air purity gets examined by the machine’s sensors and is constantly monitored. It also has a sense of what level of speed the fan should spin depending on your room.
  • Sleeping mode: If you like your nights to be quiet, you’ll love this feature. It will operate on the minimum noise possible. No sleeping babies will be disturbed.
  • Clock: Do you often forget to turn your appliances off? This feature will be plenty of help with its timer if you only want your purifier to run for limited hours. 
  • Filter replacement indicator: No need to make estimates about your purifier’s filter expiration with this feature. Remembering is a task you can leave to the machine itself. Some advanced machines can predict the time for replacement by analyzing the air quality and usage time. 
  • App: An application makes things a lot easier. You can control your home’s air quality even when you’re far away, and that’s no less than having the ability to control the weather! 
  • Fan speed settings: It’s always nice to be able to turn things up when you feel the need for it. The lowest fan speed will give you some quiet time. The speed settings can range from one to four

All things considered, air purifiers do work but probably not to the mindblowing extent of the way they’re advertised. 

The capability of an air purifier is mainly dependent on what kind of filter they use, the type of environment or area you live in, whether they use ionizers or not, and all sorts of things. 

There’s no scientific research linking air purifiers to getting rid of Covid from the surroundings. 

Keep in mind that air purifiers are expensive and run on electricity. They have to be kept in check and maintained from time to time. These things might be a lot to do if you don’t have the time or resources. It would be best to think about whether this is an absolute necessity.
