Understanding Common Indoor Air Pollutants and the Need for an Air Purifier

Indoor air quality often gets contaminated by various pollutants that could harm your health. Dust mites, pollen, pet dander, and mould spores float around in the air we breathe at home.

These allergens can trigger reactions in sensitive individuals, leading to symptoms such as sneezing, coughing, or asthma attacks. Everyday activities like cooking on a gas stove release nitrogen dioxide and other potentially toxic fumes into your living space.

Volatile organic compounds (VOCs) seep from paints, furniture varnishes and cleaning products adding to the indoor cocktail of airborne chemicals.

Air purifiers provide a line of defence against these invisible enemies. Equipped with filters like activated carbon and HEPA filters, they capture particles as small as 0.3 microns – much smaller than the width of a human hair! Such filtration systems are especially crucial for those with allergies or respiratory conditions who need cleaner air to improve sleep quality and overall well-being.

While opening windows may offer some relief by ventilating spaces with outdoor air, it’s often not enough to counteract the build-up of contaminants from everyday living – making air purifiers an essential addition to maintain cleaner indoor environments.

Installation Process of an Air Purifier

Embarking on the installation of your air purifier is a straightforward task when equipped with the right guidance. It involves initial setup, strategic positioning, and ensuring optimal air passage to defend your home against common indoor pollutants.

Step 1: Installing the air filter

Before installing the air filter, locate the airflow arrows on it. They guide you in inserting the filter in the correct direction, ensuring clean air flows smoothly through your purifier.

Positioning it backwards can restrict airflow and reduce efficiency, so take care to get this right.

Secure the filter firmly within its designated slot inside the air purifier. A properly installed filter traps pollutants effectively and maintains optimal indoor air quality (IAQ).

It’s a pivotal step for safeguarding against common contaminants like dust, pollen, and smoke that may circulate in home offices or living spaces.

Step 2: Positioning the purifier

Choose a spot for your air purifier where it can breathe freely and work its magic. Make sure the location is away from obstructions like furniture or curtains which can block airflow.

A proper setting ensures your device captures more pollutants, giving you cleaner air faster.

Ensure the surface you place your purifier on is both level and solid to prevent any operational mishaps, such as water leaks. Avoid wedging the unit into tight spots; instead, select an area with ample space around it to allow for unrestricted air intake and delivery.

This strategy maximises the effectiveness of your device in maintaining indoor air quality at optimal levels.

Step 3: Ensuring unblocked grilles

To ensure your air purifier functions at its best, maintain clear space around the grilles. These are the vents through which your device breathes in room air and releases purified air back into the environment.

Blocking these critical pathways hampers air intake and can seriously undermine the purification process. Airflow should be smooth and uninterrupted, so keep furniture, curtains, and other objects away from these areas.

Regularly check that nothing obstructs the path of clean airflow to and from your purifier. Plants, books, or decor items placed too close could reduce efficiency, leaving some pollutants untouched by the filtration system.

Provide a buffer zone around your machine’s grilles for peace of mind that you’re enjoying cleaner air without obstructing key ventilation points.

Where to Place Your Air Purifier

Choosing the ideal location for your air purifier is critical to maximise its efficiency and ensure you breathe the cleanest air possible; discover more on optimising placement within your home or office space in our detailed guide.

Near worst air pollutants

Place your air purifier close to the main sources of air contamination in your home. This might be near a kitchen where cooking fumes and smells fill the room or beside a wood-burning fireplace responsible for smoke and particulate pollution.

Target these areas because your air purifier is designed to capture pollutants at their peak concentrations, improving the clean air delivery rate throughout the space.

Consider the breathability and comfort of your living environment by positioning an air purifier near spots that generate smoke, odour, or mould issues. Doing so directly tackles these concentrated pockets of poor-quality air, ensuring fresher breathing conditions for anyone with allergies or respiratory concerns.

Ensure it’s strategically placed to allow unobstructed airflow through its filters for optimal performance.

3-5 feet off the ground

Elevating your air purifier ensures that clean, filtered air circulates effectively throughout the room. By situating it 1-1.5 metres off the ground, you take advantage of the natural airflow patterns in your home.

This height range is particularly beneficial as it corresponds with most people’s breathing zone, which means fewer pollutants are likely to be inhaled directly.

Secure your device on a sturdy piece of furniture like a chest of drawers or a shelf that can handle its weight safely. Ensure there’s at least 15 cm clearance from any wall to prevent obstructions and allow for proper exhaust and intake of air.

This setup not only maximises the efficiency of your air purification system but also subtly integrates it into the decor without making it a focal point in your space.

Areas with the highest airflow

Placing your air purifier in areas with the highest airflow maximises its efficiency. Doorways, open walls near passageways, and close to windows tend to have stronger air currents due to natural movements from outside and within different rooms.

Positioning your device here lets it capture more pollutants as they move around. Make sure the space allows for unobstructed access to the purifier’s intake and output sections so that it can pull in dirty air and release clean air effectively.

Ensure your home gets the best out of its purifier by keeping these zones clear of furniture or curtains that could hinder air movement. It’s essential for optimal performance that your purifier interacts continuously with a steady flow of indoor air, capturing tiny particles before circulating cleaner breaths back into the room.

For homes with central heating and cooling systems, placing an air purifier near an air handler helps filter out contaminants at their source, enhancing overall indoor quality.

Away from corners and obstacles

Make sure your air purifier isn’t tucked away in a corner. Corners can trap pollutants and restrict airflow, making it harder for the device to pull in dirty air and push out clean air.

This reduced circulation means your purifier won’t work as well as it should. Keep it at least a few feet from walls or large pieces of furniture that could block its intake or outlet vents.

Your purifier needs space to breathe, too. Avoid putting obstacles near it that could disrupt air flow into the machine. Without enough room, even the most powerful purifiers struggle to perform efficiently, leaving pockets of polluted air untouched throughout your home.

Give the unit ample clearance on all sides so fresh, filtered air can circulate freely around your living space, helping you breathe more easily without obstruction.

Additional Placement Guidelines

Delving into the nuances of air purifier installation enhances its efficacy; these extra tips help tailor placement to your specific environment, optimising clean air delivery throughout your space.

Considering ambient factors such as humidity and nearby electronics can significantly influence the performance and longevity of your device.

Avoiding high-humidity places

Placing your air purifier in a high-humidity area makes it work harder than necessary. Moist environments, like bathrooms or near the kitchen hood, can impede the effectiveness of your device.

The extra moisture in the air means your purifier needs to generate more airflow which could strain its system and reduce efficiency.

To get the best out of your air purifier, position it away from places where moisture builds up. Consider using a dehumidifier in spaces like basements where dampness prevails.

This will help maintain optimal operating conditions for your air purifier, ensuring it captures pollutants effectively without overworking itself due to excess humidity.

Keeping distance from electronic devices

Position your air purifier at least 2-4 feet away from electronic devices like TVs, computers, and microwaves. This helps prevent electromagnetic interference that could hinder the performance of the purifier and your gadgets.

It’s important for an air cleaner to run smoothly without disruptions caused by other electrical items.

Ensure it is placed in a spot where routine movement won’t disturb its operation. Electronics can emit heat and other particles that might compromise the efficiency of your air filtering system.

By keeping distance, you also ensure that dust and pollutants are captured more effectively as they circulate through the room’s airspace rather than being drawn straight into heated or electronic areas where they may settle quickly without being filtered.

Moving the air purifier around for maximum efficiency

To maintain peak performance, consider relocating your air purifier from time to time. This ensures it tackles different concentrations of pollutants as they arise in various areas of the room.

For instance, after cooking, move the unit closer to the kitchen to neutralise lingering food odours and additional particle matter. Similarly, if outside pollution levels spike or someone smokes indoors, shifting the air purifier near an open window or door can be beneficial.

Changing its location is also important when seasonal allergies come into play. Airborne pollen tends to concentrate in certain parts of a home; moving your purifier can provide targeted relief where needed most.

Ensure that each new placement follows the rule: keep it at least six inches away from walls and furniture for optimal airflow and performance.

Keep track of changes in your indoor air quality by occasionally adjusting your air purifier’s position based on activities and external factors like outdoor air pollution or high pollen counts.

By doing so, you’ll effectively reduce exposure to harmful pollutants throughout varying conditions within your living space.

How Many Air Purifiers are Needed

Determining the correct number of air purifiers for your space hinges on several factors, including room size and individual health needs. For those sensitive to airborne particles or living with allergies, multiple units might be necessary to maintain cleaner air throughout their home.

It’s important to choose air purifiers with an appropriate clean air delivery rate (CADR) that matches the square footage of each room you want to treat.

In homes where heating and air conditioning systems circulate air continuously, strategically placed air purifiers can enhance overall indoor air quality. Larger areas may require a higher capacity unit or multiple devices positioned around the space for adequate filtration.

Consult manufacturer guidelines and factor in variables such as ceiling height and room layout when calculating how many purifiers will effectively combat pollutants like CO2 gases, germs from flu viruses such as COVID-19, cooking odours from cookers, or smoke from cigarettes.

Always match each unit’s capabilities with the specific requirements of your living environment for optimal results.


Ensuring your air purifier is properly installed makes a huge difference in efficiency. Choose the best spot, and you’ll breathe easier knowing you’re combating indoor pollutants effectively.

Remember to give your device space to work its magic, maintaining clear airways for optimal functioning. Place it thoughtfully within your living areas to maximise clean air delivery throughout your home.
