The small ones that can be used inside the home are stand-alone units. If the house is larger, a bigger air purifier can be affixed in the house’s Air Handler Unit (AHU). Commercial buildings and establishments need a special kind of air purifiers that can be installed on the building’s HVAC (Heating Ventilation Air Conditioning) unit. There are two kinds of air purifiers: active and passive. Active air purifiers use air purifying technologies like ionisation, ozone, and UV light. While passive air purifiers are those that are equipped with filters.

Although many people love this product, it was inevitable that some have voiced out concerns regarding the reliability of air purifiers when it comes to its effects in the body. Given that it is an electronic machine, some people could not help but think, “Does air purifier make you sick?” The sides of truth were halved in the online world; others say that air purifiers do not make you sick, while others share their own experience about air purifiers causing them common illnesses.

(Note: Your naked eyes could see as small as 0.10 microns, so 0.03 is considered really, really tiny) Knowing that you’re breathing in pure and clean air, it adds to the comfort you feel.
  2. An air purifier can prevent allergies and other respiratory-related diseases – Do you have a seasonal allergy? Does it spike up whenever you inhale something that could trigger it? Well, consider an air purifier as your life-saver. This device, because it’s designed to eliminate up to 99.97% (depending on the device model) of indoor air pollution, the chances of causing allergies dramatically decreases. Some air purifier brands produce passive devices; those that are designed with HEPA filters are even equipped with Activated Carbon Filters. These filters get rid of air odor caused by molds and other things.

Can an air purifier make me sick?

The truth is, yes and no. Yes, an air purifier can make you sick, but NOT because of how it was made; and no, an air purifier (mostly) cannot make you sick (depending on the kind of air purifier), if what you are pointing out are the side effects this device can bring to your health. But if you’re wondering how an air purifier can, by any chance, make you sick or feel sick, here are some possible reasons:

  1. Your air purifier is wrongly placed inside your home – A common mistake that most consumers commit whenever they purchase a brand new air purifier is they place it on wrong spot. Chances are, when the person is exposed near the air purifier for long hours, it can cause dizzy spells, dry sinuses, and nose bleeds. Low humidity can even contribute to worsening the case because when there is not enough humidity inside the room, having a dry or sore throat is easily caught. Keep in mind that placing your air purifier on key areas is important. Make sure that it is located not too near and not too far from the place where you and your family members always hang-out at home. Say, in the living room, it’s good to place it on the corner or near the windows, but not near the sofa where you can be closely exposed. In the bed room, it’s ideal to place it a few meters away from the bed, but not on the bedside, especially if you have a case of sleep apnea. Long exposure on the device might trigger the condition while sleeping. Also, keep in mind that you must not place an air purifier adjacent to another air purifier, especially if you are using high-powered units.
  2. Your air purifier is not wellmaintained – Some air purifiers, especially the ones equipped with filters, need maintenance and parts replacements regularly. Some device models need filter replacements every six months, while some need cleaning every week or two. When the filters are dust- and germ-packed, the air purifier will have a hard time performing the way it should. Thus, it will not be able to eliminate air-borne particles and bacteria at optimum performance. The worse that could happen is it will produce air that can cause adverse effects to the body. Always remember that any electronic device, when misused and abused, can function improperly. Replace filters on-time. Buy extra filter sets for future use; you can always purchase replacements from If your air purifier does not have filters, make sure that you are cleaning it every month or two. If you have time, have your device maintained on service centers regularly.
  3. Your air purifier is properly placed, but elevated – Positioning your air purifier on a higher place plays a crucial part in producing clean oxygen. When the altitude is high, there is lesser oxygen—and this can pose a problem in-line with the device’s performance. When the air purifier unit is placed on a higher place, it will produce lesser oxygen, thus, making the supply scarce for you. When your body breathes in less oxygen, it can cause breathing difficulties, headaches, and worse, dizzy spells.

The information mentioned above are just few of the possible reasons how an air purifier can make you sick in cases that do not have anything to do with how the product was designed. To back-up your worries with knowledge, here are some few pointers:

  1. No, an air purifier does not cause sore throatat least, the ones that are equipped with air filters – As a matter of fact, the device prevents you from having sore throat because it cleanses the air from dust mites, pet dander, pollen, mold spores, bacteria, and anything that might irritate the your throat. Now, there are air purifiers that can possibly cause sore throat, and these are the ionizers. An Ionization Air Purifying Technology does not require filtration, but it purifies air through negatively charged ions. When these negatively charged ions trap the positively charged dusts and air-borne particles, the latter are eliminated. Although the air is purified, there could be cases that ionization can cause sore throats because a few ozone particles are emitted.
  2. No, air purifiers don’t cause coughing – An air purifiers cleanses the air and one of the benefits that you can get from this is your chances of getting coughs are lessened. If your cough persists, there is probably something that is worsening it, but it’s definitely not the air purifier. Ionic purifiers have a chance of irritating the throat, but it will not trigger coughing. If you are to purchase an air purifier, you might want to consider ordering a dust air purifier; the latter is good for people who have uncontrollable coughs.
  3. No, air purifiers don’t cause headaches – Even the ionic purifiers. Although the latter emits little amounts of ozone, still, it will not be enough to even cause a headache. There are many factors that might cause headaches, but an air purifier is not one of it.
  4. No, air purifiers don’t cause nose bleeds – One of the causes of nose bleed is when the sinuses dry up; and air purifiers don’t contribute to drying up the sinuses and throat. One of the culprits when a person gets nose bleed is dry air. When there is low humidity, the air gets drier and crisper, drying up the nostrils, sinuses, and the throat. When these internal parts are deprived of moisture, they get irritated and eventually, they bleed or become sore; hence, the nose bleed. If you’re one of those consumers who get frequent nose bleeding, it would be wise to consider buying a humidifier, so comes winter or summer (when air is dry at most), you can still regulate the humidity inside your house. If you have a good budget, you can purchase combo units; these are air purifier units with humidifying function. Having a combo unit inside the house gives you the confidence that indoor air is purified and at the same time, humidity is controlled. Also, you can order a dehumidifier. The latter, unlike the humidifier, decreases humidity in an area. Too much humidity also causes nose bleed, so for a fully equipped home, get yourself an air purifier, a humidifier, and a dehumidifier.


Air purifiers don’t make you sick. Keep in mind that these devices, over the years, were carefully designed and innovated to meet consumer standards. Many air purifier brands dedicated many years to precisely engineer their products, so that these will only bring the best and purest air without any harmful side effects. Although, among many air purifier technologies, filtration is the best choice for most consumers. Ozone, ionisation, and UV light technology are seldom picked because of the potential side effects. There are numerous brands in the market that offer air purifier with multiple-stage filtration. Some can even eliminate air particulates are small as 0.003 microns. While some are equipped with special filters like Activated Carbon and organic filters to meet specific consumer needs. Nevertheless, do not fret buying your very own air filter because it is a long-term investment for your health. What are you waiting for?
