How to calculate the purification area of air purifier

If you want to know the purification area of an air purifier, you need to know the CADR value of the purifier first. Then what is the CADR value?
CADR is the acronym of clean air delivery rate. It can be simply understood as the total amount of clean air output by air purifier after removing solid particles per unit time. It is an important index to evaluate the purification performance of an air purifier.
The internationally recognized “CADR value” is the result of testing the air purifier under certain testing conditions by AHAM. Generally speaking, the larger the power of the detected air purifier is, the higher the output value of clean air is, and the larger the applicable area is.


According to international practice, a qualified air purifier can purify indoor air five times per hour. So, how can we judge the room area that can be purified by the CADR  value of an air purifier?
In fact, we can easily get the result through a formula【 Applicable area s (M2) = 12F / 60H] in the formula, s on the left represents the area to be calculated, f on the right is the maximum air output of the air purifier, i.e. CADR value, and H is the floor height of the room, generally calculated as 2.8m. According to the international standard, the indoor air should be purified five times in an hour, that is, every 12 minutes, so the numerator and denominator are multiplied by 12 and 60.

be careful:
However, the applicable area of the air purifier is only a reference data. Due to the influence of the air exchange volume in the room, the floor height of the house and the number of furniture placed in the room, the specific value of the applicable area of the house is not the same, and the so-called applicable area is only a reference value.
In addition, many air purifiers also have the function of removing formaldehyde, and the CADR value of purifying formaldehyde is generally weaker than that of purifying particulate matter. So in the purchase of air purifier must be consistent with their actual needs.

In summer, formaldehyde air purifier is more needed

In general, users are used to decorating rooms in spring, and “let the wind” exhaust poison for newly decorated rooms in summer. After the new house is decorated, it can be moved in 3-6 months, but this does not mean that the pollutants are completely dispersed.
Some experiments show that the formaldehyde emitted from wooden furniture and floor will increase the concentration of formaldehyde in the air by 0.15 to 0.37 times when the indoor temperature rises by 1 ℃. In summer, indoor and outdoor are in a high temperature and humid environment, which will accelerate the release of formaldehyde in furniture and other decoration materials. Especially in summer, indoor and outdoor are in a relatively high temperature and humid environment, which will accelerate the release of formaldehyde. Most users will smell pungent smell in the newly decorated rooms. Therefore, for the new house decoration time is short, the new home bought a few pieces of furniture, the old house for local decoration, especially in summer should pay attention to formaldehyde.
In response, Olansi alls for the reasonable use of air purifiers with formaldehyde removal function in summer, which can improve and improve air quality and reduce indoor air pollution.

5 Benefits of Using UV light air purifier

What are UV light air purifiers?

UV lighting is a special type of radiation that can’t be seen by the naked eye because it’s part of the invisible section that makes up the electromagnetic spectrum.

To be precise, its wavelength is from 400 nm (750 THz) to 10 nm (30 PHz), shorter than that of visible light but longer than X-rays

It causes sunburns by destroying cells, and this cell-destroying ability is what makes it effective for destroying air impurities, specifically mold and mildew.

Ultraviolet light is a form of light that rests just outside the visible spectrum for humans. The wavelength of UV light is shorter than visible light, but longer than X-rays. It’s estimated that UV light makes up about 10% of the sun’s output.

What also makes UV light unique is that it’s divided into three sub-bands, UV-A, UV-B, and UV-C.

You’ve probably heard of UV-A and UV-B light before because they’re heavily marketed on sunscreen lotions.

These types of UV lights are the ones that come from the sun and cause sunburn and skin cancers.

UV-C light, on the other hand, is a powerful form of radiation that’s harmless to people, but excellent at killing microorganisms, such as germs and viruses.

In fact, a recent lab test was performed where non-critical patient care items were exposed to two 30 sec. UV-C light cycles and the number of bacteria on 40 out of 51 target sites were reduced to below detectable levels

Of course, UV light is also created artificially, by technologies that include arc welders, tanning beds, black lights, and some forms of air purifiers.

UV air purifiers are designed to use short-wave ultraviolet light (UV-C light) to inactivate airborne pathogens and microorganisms like mold, bacteria and viruses. They have the same ultimate goal of all air purifiers: to reduce indoor air pollutants. The technology is also referred to as UV germicidal irradiation, or UVGI air purifiers. This is different from other air purifier technologies that contain UV light technology but do not use it directly against air pollutants.

On the market, UV-C air purifiers are currently sold as stand-alone, freestanding devices or as systems installed into pre-existing residential or commercial HVAC units. As air is forced through the device, it passes UV lamps, which directly attempt to disinfect the air by means of germicidal irradiation. The biggest safety concern is that ozone may be generated during this process.

Rarely a stand-alone product, UV-C light air purifiers often require additional systems for full effectiveness and are most often included in larger High-efficiency Particulate Arrestance (HEPA) air filtration systems. In fact, the EPA says that a UV-C air purifier does not seem effective as a stand-alone unit because it cannot trap or remove particles.

How do uv air purifier work?

As air passes through the air purifier, it eventually goes through a small internal chamber that exposes the particles to UV light.

The light is not emitted into the room, nor can you see it.

A UV light purifier works by disrupting the core DNA of these pathogens.

This prevents them from multiplying and causing you to become sick.

As you can see, UV lights are the king of killing all unwanted bacteria, germs, and viruses.

When combining this type of technology with a HEPA filter or Ionic generator, you can rest assured that wherever you decide to place the air purifying device, you’ll have the cleanest, most sterile air possible due to the use of a UV light cleaner.

5 Benefits of Using UV light air purifier

In the day to day, we are faced with several problems that can affect our respiratory health and ours. However, the use of an UV light air purifier can end up making our lives much easier. But, there is the basic problem: people do not know what benefits this device gives us. Well here, we will list about 5 benefits that will make us understand, how good this device can be for our health.


1- Filter Pet Hairs and Dandruff

Our pets leave hair and dandruff everywhere. Cat dander is especially small and sticky when deposited on a surface. The UV light air purifiers have a prefilter that filters the hairs in suspension and the HEPA Filter filters the dandruff.

2- Eliminates odors

As we have said before, UV light air purifiers mostly have an active carbon filter. This filter is responsible for trapping fundamentally organic compounds present in the air and responsible for the bad smell. We can call this filter the odor filter. UV light air purifiers for smokers are very useful since they not only purify the air they breathe but also eliminate the smell of tobacco.

The smell of food, the smell of moisture, the smell of your pet … Active carbon is an extremely porous material that attracts all these bad smells and eliminates them.

3- Cleaning Reinforcement

When we do the cleaning of a room, there are always particles in suspension that when we have finished will be deposited again on the floor, furniture and finally, on any surface. An UV light air purifier serves to filter these particles constantly. If you remove them, they are not deposited and if they are not deposited, we do not have to clean them! This does not mean that you are going to release the mop and the dust cloth so that it will undoubtedly be a support for cleaning.

4- Mold-free spaces

Mold proliferates in humid environments; this is a reality. It produces small spores invisible to the eye that are deposited on any surface, toys, carpets, curtains, etc. Mold is a common trigger for allergies and asthma. What does this mean? Well, he is responsible for making them worse and that is why sometimes we listen I am allergic to mold.

UV light air purifiers are effective in removing mold spores from the environment, their HEPA filter captures mold spores and removes them.

Now we recommend that if the humidity in the environment is very high use a good dehumidifier and root cuts the problem. If you reduce humidity, mold will not find its comfort habitat and therefore will not proliferate.

5- Improvement of respiratory health

There are many particles in the air that cause damage to our respiratory health, especially if we are allergic. Pollen and dust become our worst enemies, any presence of them ends up generating a lot of cough and discomfort. An UV light air purifier will be mainly responsible for keeping us calm in that aspect, helping to filter dust and pollen giving us a healthier air to breathe.
