What Do Air Purifiers Help With? This is a question that many of us have asked ourselves, especially in recent times when the importance of clean air has been highlighted more than ever. If you’re considering purchasing an air purifier, you’re likely wondering what benefits it can provide. In this comprehensive guide, we’ll explore the different types of pollutants that air purifiers can help with, how they work to improve indoor air quality, and what they can’t do. We’ll also delve into some real-life examples and take a storytelling approach to make the content more engaging and relatable. So, let’s dive in!

What Do Air Purifiers Help With? The Ultimate Guide

How Do Air Purifiers Work?

Before we delve into the specific pollutants that air purifiers can help with, it’s crucial to understand how these devices work. Most air purifiers use one or more filters to trap pollutants as they pass through the device. These filters may contain materials such as activated carbon, HEPA (high-efficiency particulate air) filters, or UV lights.

Activated carbon filters absorb odors and gases in addition to trapping larger particles like dust and pet dander. HEPA filters capture up to 99.97% of airborne particles as small as 0.3 microns, including allergens like pollen and mold spores. UV lights kill bacteria and viruses by damaging their DNA so they cannot reproduce.

In addition to these, some air purifiers use an electrostatic charge to attract and capture particles. This is particularly useful for trapping smaller particles that might otherwise slip through the other filters.

Common Indoor Pollutants

There are many types of indoor pollutants that can negatively affect your health if not addressed properly. Here are some of the most common types:


Allergens such as pollen, dust mites, pet dander, and mold spores are airborne particles often found inside homes that cause allergies or aggravate asthma symptoms.


Volatile organic compounds (VOCs) come from household products such as cleaning supplies, paints, carpets/furniture made with synthetic materials & adhesives which create harmful gasses when released into the atmosphere causing respiratory problems & headaches over time.


Smoke is a major contributor towards poor indoor air quality; tobacco smoke contains thousands of chemicals which impair your lungs if inhaled for long durations causing heart diseases, breathing problems, and allergies.

Bacteria & Viruses

Bacteria and viruses can cause a range of illnesses from the common cold to severe respiratory infections. They are often spread through contact with contaminated surfaces or by inhaling airborne droplets.

What Can Air Purifiers Help With?

Now that we’ve identified some common indoor pollutants, let’s discuss how air purifiers can help with these issues:


HEPA filters in certain air purifiers remove allergens such as pollen, pet dander, dust mites & mold spores which triggers allergic reactions.


Air purifiers capture asthma triggers like pet hair and fur, cigarette smoke/pollutants that could cause chest tightness/wheezing making it easier for an asthmatic to breathe better indoors.


Activated carbon filters absorb harmful chemicals found in everyday household products reducing the risk of exposure leading to a healthier environment.


Carbon and HEPA filters effectively trap smoke particles improving overall air quality & reducing health risks associated with regular inhalation of tobacco smoke causes cancers over time.


UV-C lights provide an extra layer of protection against bacteria and viruses by damaging their DNA structure so they cannot reproduce leading to reduced chances of infection/illness.

What Don’t Air Purifiers Help With?

While air purifiers can significantly improve indoor air quality, they are not a cure-all solution. There are certain pollutants that air purifiers can’t effectively remove:


Air purifiers can’t remove gases like radon or volatile organic compounds (VOCs) from household products.

Settled Allergens

They also can’t remove allergens that have settled into carpets and upholstery.


Air purifiers may not be particularly useful for removing mold.

Nicotine and Other Gaseous Pollutants

Air purifiers do little to remove nicotine from indoor air.

Animal Dander from Involuntary Rodent Infestations

Air purifiers may not be particularly useful for removing animal dander, especially from involuntary rodent infestations.

Cockroach Allergens

Air purifiers may not be particularly useful for removing cockroach allergens.

Some Types of VOCs

Air purifiers may not be particularly useful for removing some types of VOCs.

Larger, Heavier Allergens

Air purifiers may not be particularly useful for removing larger, heavier allergens, such as dust mites and pollen, which may settle to the ground more quickly than air purifiers can capture them.


Investing in an air purifier is a great option for those looking to improve their indoor air quality & maintain good health by removing dangerous toxins from their homes/offices gradually over time. As outlined above it offers many benefits including reducing allergy symptoms/asthma, reducing VOCs in the air, and improving overall respiratory health. With this ultimate guide & understanding of how air purifiers work along with types of pollutants they can help remove it will make you a well informed buyer while browsing through different options available to you. Make sure to choose an appropriate-sized air purifier for your room or space according to its recommended coverage area by considering multiple factors that affect indoor air quality levels such as the number of family members living there pets, allergy symptoms etc., which will play a vital role in better outcomes. Remembering basic HVAC tips & tricks will go a long way in maintaining healthy environments for ourselves and our loved ones.


Can air purifiers help with allergies?

Yes, air purifiers can be helpful for people with allergies as they are designed to capture and remove harmful particles from the air, such as pollen, dust mites, pet dander, and mold spores.

Are air purifiers effective in removing cigarette smoke?

Air purifiers can help reduce cigarette smoke in enclosed spaces by capturing and filtering out the chemicals that cause the unpleasant odor and health risks associated with smoking. However, it may not completely eliminate all traces of smoke or its smell.

Do air purifiers help with viruses like COVID-19?

While there is still a lot unknown about how COVID-19 spreads through the air indoors, some studies suggest that using an air purifier can help reduce transmission of airborne particles when combined with other preventive measures like social distancing and wearing masks. However, it is important to note that no single device or tool can completely prevent the spread of viruses on their own.
