Do Air Purifiers Cause Nose Bleed?

Nose bleed. It’s not painful per se, but the mere fact that you realize that a crimson liquid is gushing out of your nostrils is enough to give you the panic. Although nosebleed is caused by many things, one of these is the weather. Seasons change and when it does, the body adjusts to the outdoor and indoor temperature. One of the body parts that get easily affected when the weather changes is the nose passageway; and if it is sensitive enough, you might get a nosebleed.

If you live in a country where seasons change four times a year, you probably are aware that devices can help you cope up during season transitions. Take for example, the air purifier. This device comes in handy not only during hot or cold months, but it’s a unit that you’re going to need for all seasons! But did you know that even an air purifier can cause nose bleeds?


An air purifier typically purifies the air in an indoor or enclosed area. Its main purpose is to turn polluted indoor air into clean breathable air through different technologies like ionization, filtration, ozone, and ultraviolet light. This device can get rid of various air contaminants like pet dander, dusts, mold spores, pollen, and even second-hand smoke. Many consumers have testified that air purifier greatly helped them in their daily living. Because air purifiers get rid of indoor air pollution, seasonal allergies, and respiratory conditions like bronchitis and asthma have  higher rates of prevention. Some even considered air purifier as a life saver.

Air Purifier Health Benefits

Not familiar with what good an air purifier does inside the home? Here are some of the benefits when you have this:

  • If you’re suffering from seasonal allergies or are just allergic to dusts, pollens, and other tiny air particles, an air purifier can prevent your allergies from spiking up. Most of the air purifier products in the market, especially the passive types that are equipped with HEPA filters, can get rid of air contaminants as small as 0.03 microns. If you’re not familiar with “microns”, consider that the smallest particle that your naked eyes can see is about 0.10 microns.
  • If you are frequently getting sore throat, an air purifier can help in lessening its symptoms. Air particulates can irritate your nose passageway and throat whenever you breathe in. Having an air purifier inside your home will give you the confidence that you’re breathing in pure and clean air.
  • If you have just given birth to a beautiful baby, a high-quality air purifier can also come handy to your parent duties. Newly born babies’ lungs are still developing, that is why it’s crucial and important to give them the freshest air they could breathe in. Having an air purifier inside your home will definitely give you a sigh of relief, knowing that your baby it not being affected by indoor air pollution.
  • If you’re one of those who are born with sensitive skin and chronic skin irritability is taking the joy from your day, you’d probably want to consider having an air purifier inside your home. This device is also an effective tool in reducing skin conditions like rashes and dryness—both of which are directly linked to skin irritation.

Air Purifier, Nose Bleeds, and Other Health Concerns

Although most consumers love air purifiers because of the health benefit it gives, not everyone shared positive views about this. Some people expressed their concerns about the side effects of having an air purifier at home. Does air purifier make you sick? Does it cause other common illnesses like sore throat, dry throat, or skin irritation? Do air purifiers cause nose bleed? These are just some of the questions most consumers might have in mind—especially the latter. But the truth is, if you’re wondering if an air purifier causes nose bleed, yes it does. But fret not! It’s not because how your air purifier was made. This device, long before you were even born, was invented and through the years, manufacturers have carefully designed and re-designed the air purifier to meet high consumer standards. And if you’re wondering, an air purifier causes nose bleed because of the possible reasons:

  1. Your air purifier is not located or placed on an ideal spot – Most consumers commit a common mistake when placing their air purifiers at home. They put it on a spot where they usually hang out or chill. Of course, one would reason out that to get the most out of the device’s air purifying activity, it should be placed near. This is actually a wrong practice. Keep in mind that although an air purifier is carefully designed to give you the freshest of air, prolonged exposure near this device may cause the sinuses and throat to dry up; thus, causing dizzy spells, headaches, and even nose bleeds. In worse cases, if the consumer places an air purifier on the bed side and he’s suffering from sleep apnea, this has the possibility of triggering the condition. Keep in mind that the key areas in the room where an air purifier must be placed are the corners of the house. Don’t place two units adjacent to each other, especially if you’re using high-powered air purifiers.
  • Your air purifier is highly elevated – When you’re in a place where there is higher altitude, the lesser oxygen you can get from the air. This also applies when positioning your air purifier unit. The latter recycles air, especially the passive units that are equipped with HEPA filters, and pushes through purified air. If the air purifier is placed in an elevated area, because of the higher altitude, lesser oxygen is provided. Less oxygen intake also contributes to various body reactions like nose bleeds. To prevent this from happening, place your air purifier at ground level for it to get and produce enough oxygen.
  • It’s not the device, it’s the humidity! – The amount of water vapour in the air contributes in keeping your sinuses in good condition. When there is less humidity in an area, the air becomes drier and crisper, drying up the sinuses, nose passageway, and throat. This causes nose bleed. That is why there are some brands that came up with combo units: an air purifier with a built-in humidifier. Not only does this unit purify the air, but you can also opt to simultaneous air purifying and humidifying functions. It’s also the same when there is too much humidity; it triggers nasal congestion which can also cause nose bleed. For a situation like this, you can, instead, use a dehumidifier. This device releases warmer air and eventually lessens the humidity of an area.

To help you choose the right brand and product for your consumer needs, here are some air purifier, combo units, and dehumidifier products that you might want to consider buying:

Do not feel discouraged about purchasing an air purifier for your home, because if you know how to take care of your home appliance, then there is confidence when using them. If you’re living in a place where the humidity is good, you can opt to buying a stand-alone air purifier; but if you’re located in a place where humidity must be regulated during change of seasons, then it’s wise to invest for an air purifier and humidifier combo unit. For better results, it’s also good to purchase a separate dehumidifier, so when humidity hikes on certain weather conditions, you won’t have to worry about breathing in bad indoor air.
