They say nothing is as essential to your health as clean fresh air.

But where to start?

Through this article, you’ll discover:

    However, with the real estate market investing in buildings designed to be increasingly airtight and energy-efficient, indoor contaminants are becoming an increasing problem in homes.

    These impurities include things like cigarette smoke, dust, chemical fumes, pollen, mould spores, allergens, pet dander, bacteria, and viruses.

    It gets worse…

    According to the Environmental Protection Agency (EPA), indoor air is more susceptible to pollution than the outdoors, even in urban areas.

    With many people spending much of their time indoors, the health risks of indoor air pollution are a significant issue and an air purifier seems like the best solution.

    That said, how can you ensure that you get the perfect air purifier to combat these issues? I’m going to tell you how in a minute.

    But first…

    What's an Air Purifier

    Just What’s an Air Purifier?

    An air purifier or air cleaner is an electronic device that draws in the air of a room.

    Pulling it through an effective system of filters that capture airborne pollutants before blowing out fresh, crisp, and clean air back into your living space.


    When you’re out shopping for an air purifier system, you need to ensure that you check the rating for room size, usually indicated on the package.

    Ideally, you should opt for an air unit that can handle a room slightly larger than the one you will be using it in.

    Types of Filters

    The Different Types of Filters You’ll Find

    There are several types of air filters that vary in the kinds of screens and how they get rid of airborne contaminants.

    Most air purifier models combine filter types for maximum results and high performance.

    Some of the most common filters air purifiers feature include:

    #1. The Activated Carbon Filter

    This filter is perfect for removing smoke, gases, and odours from a room.

    However, it does very little when it comes to dust and allergens.

    Most air purifier systems use the activated carbon for odour control, while using another type of filter for particles.

    Moreover, carbon filters need periodic replacement and so can be costly.

    #2. The HEPA Filter

    The well-known high-efficiency particulate air filter is able to get rid of 99% of airborne particles measuring 0.3 microns1  or more in the air.

    Meaning that dust, mould spores, pollen, dander, and most bacteria can’t pass through the filter.

    The best hepa filters are proven to be perfect for those with allergies or respiratory conditions and are the most sought-after type of air purifiers.

    But there’s something you should keep in mind with this filter:

    While some HEPA air purifiers claim to have a “long-lasting” filter that only requires occasional vacuuming, in reality, it’s very challenging to vacuum the screen thoroughly.

    More often than not, you need to make sure that you replace the HEPA filters periodically – anywhere from a few months to once a year, depending on how often you use it.

    #3. The Pre-filter

    Most air purifying systems use the pre-filter to trap the biggest particles in the air before they reach the primary filter.

    Having the pre-filter saves your air purifier’s more expensive primary filter from wear and tear, meaning you won’t have to change it as often.

    #4. Electrostatic Filter

    This one works by pulling air through an electronic field, forming an electrical charge that captures particles on a charged metal plate.

    It’s not very efficient in trapping bacteria, but it’s one of the most reliable filters when it comes to allergens, dust, and some gases and odours.


    Unlike its counterparts, the electrostatic collection plates require periodic cleaning, but there are no filters to replace, thus saving your pockets.

    #5. Ionizer

    Most air purifier manufactures recommend that you use an ionizer in conjunction with a filtered device.

    It discharges electrons into the air, which attract dust and other particles.

    These massive “clumps” of particulate matter are more stress-free for your air purifying system’s filter to capture.

    Nevertheless, these particulates can also fall onto your carpet, fabric, or upholstery.

    On the other hand…

    Some ionizers also emit ozone2 , which is irritating to your lungs and can lead to asthma, especially in people susceptible to respiratory conditions.

    Ozone is also dangerous to pet birds or other small pets.

    Is Space a Problem

    Is Space A Problem?

    Are you stuck trying to get the perfect air purifier for your room size?

    Well, when trying to get the best air purifier for your specific room size, the first step you need to take is to figure out how much space you want your device to clean.

    Small desktop devices aren’t efficient in large-sized rooms, while heavy-duty purifiers might be overkill in your kid’s bedroom. 

    In my own experience,

    One of the best ways to get the perfect fit is to look at the “air changes per hour” specs on an air purifier.

    This can help you understand how filtration works, while also giving you an idea of how the system will work in a room of a particular size.

    If after checking this spec you’re still not sure what type of air purifier will be best for the size of your room, then it’s advisable to get a bigger purifier unit than what you think you’ll need, as long as it’s within your budget.

    What About Pets

    What about Pets?

    If you share your home with furry friends, then you’ll know that even though Meatball and Rex are good company to have around, they can be a significant source of pungent pet odour, dander, bacteria, and dirt in your living spaces.

    This is especially a problem if pet dander sets of allergies. Read about the best air purifiers for people with cat allergies.

    But wait, let me tell you something:

    There are specific air purifiers perfect for tackling these kinds of problems, like the IQAir Health Pro Plus which offers you up to 25% cleaner air.

    It also features HyperHEPA technology that traps particles of all sizes from pet dander, viruses, dust mites, and cigarette smoke.

    It’s also effective in rooms of almost all sizes, thus making it an ideal option.

    Best of all…

    In Short:

    As most home-owners and real estate developers are moving to construct more energy-efficient3  homes, some things are bound to change.

    The electric bills will go down, but discomfort due to indoor pollution will rise.

    By investing in a reliable air purifier, you’ll enjoy clean and crisp air while also saving your pockets from hospital bills.
