    What causes air pollution at home?

    While you’ll be familiar with common outdoor pollutants such as smog and car emissions, you might not be aware of the pollutants that can creep into your home. Yep, most of the time they won’t smell or be noticeable, however they can have a big impact on the quality of the air in your home. We’ve listed a few of the most common indoor pollutants you might find.


    Household dust is made up of tiny particulate matter like skin, dander, fibres and anything you might have brought in from outside on your feet or clothing, such as pollen or dirt.

    Cleaning products

    Household cleaning products can release chemicals which can linger and be irritable.

    Second-hand smoke

    Second-hand smoke comes from burning cigarettes and cigars as well as the smoke that is breathed out by a smoker.


    If the moisture in your home is too high, you might notice dampness in the walls. If untreated this can turn into mould which can be harmful when inhaled.


    Pollen is a fine powder-like substance that comes from plants. Particularly potent in the summer, it can easily make its way into your home.

    Painting & decorating

    Many decorating materials like paint release chemicals such as VOCs that can linger around in your home if not properly ventilated.

    But what effects can they have?

    These types of indoor air pollution, if breathed in over a long period of time can give you a bit of a dry cough as well as making you a little short of breath or wheezy. Bad air will also make it worse if you are allergy prone or suffer from asthma. Thankfully though, with a good air purifier, you can keep the air in your home nice and clean.
