How To Improve Indoor Air Quality: Tips From An Aircon Expert In Singapore

Many of us scarcely realise that the air we breathe indoors, where we spend most of our time, can be more polluted than the air outside. This isn’t just an inconvenience; it’s a matter of our health and well-being.

At iCare Aircon, this understanding is central to what we do.

James Tan, with his 20 years leading our team here in Singapore, has positioned iCare Aircon as a beacon in the air conditioning service industry. We’re not just about keeping you cool; it’s about ensuring the air you breathe in your homes and workplaces does wonders for your comfort and well-being.

Let us help you make that change for cleaner indoor air—it’s easier than you might think.

Key Takeaways

  • Keeping air filters clean and changing them often improves indoor air by stopping dust and allergens.
  • Using natural cleaners instead of scented products helps keep the air in your home cleaner and safer.
  • Indoor plants like spider plants can clean the air, but they don’t replace good ventilation or cleaning.
  • Regular checks and maintenance on heating systems, including checking refrigerant levels, ensure efficient operation and better air quality.
  • Air purifiers with HEPA filters are effective at catching small particles to make the indoor environment healthier.

Identify and Reduce Indoor Pollutants

We tackle indoor air pollutants by finding and lowering them. Things like radon, volatile organic compounds (VOCs), and mould spores worsen our air at home. Products inside our houses such as paints, glues, and cleaners release VOCs causing irritation or worse.

Radon gas can sneak in, raising the risks of lung cancer. We cut these dangers by keeping harmful products out and checking for radon.

Air filters catch small invaders we cannot see. Changing them often stops dust and allergens from spreading through air conditioning systems. Vacuuming with HEPA filters pulls trapped particles out of carpets and furniture.

This way, clean air flows better inside homes, making breathing easier for everyone.

Techniques for Testing Indoor Air Quality

We use low-cost kits to check for radon at home. This step is key as indoor air pollutants can be up to five times higher than outside. For ongoing problems, get help from experts.

They use tools like air sampling instruments and humidity gauges to find out what’s in the air. These devices tell us about things that can harm our health, like too much carbon dioxide or harmful chemicals.

Our team looks closely at the results from these tests. We want to make sure your living space has clean and safe air. If we find bad stuff in the air, we take steps right away to fix it.

This could mean improving how your home lets in fresh air or suggesting ways to keep harmful particles out of your indoor space.

Strategies to Control Allergens

To tackle allergens, we focus on keeping our homes clean. Dusting and vacuuming often help remove dust, pet dander, and mould. These actions cut down on allergens that pollute indoor air.

We make sure to use a vacuum cleaner with a HEPA filter for the best results. This catches even the smallest particles.

Changing furnace filters regularly is key too. A MERV-13-rated filter traps pollutants well. This step ensures air flows cleanly through heating and cooling systems. Also, we advise against burning anything indoors or using strong chemicals like air fresheners and cleaning products.

These add unwanted chemicals to the air which can trigger allergy symptoms.

Choosing and Using Air Purifiers

We always suggest investing in air purifiers with HEPA filters to help improve indoor air quality. These devices are excellent at capturing smaller particles, making the air in your home cleaner and safer.

It’s crucial to pick an air purifier that matches the size of the room for it to be effective. A small device won’t clean a large space well.

Air cleaners come in many types and sizes, but not all are good at reducing every pollutant like radon. So, we focus on those models known for their ability to pull a lot of air through the filter, improving their effectiveness at collecting pollutants.

Using these tools can make a big difference in keeping your air clean—especially important for homes in busy areas or with allergy issues.

Enhance Indoor Ventilation

We ensure fresh air flows in our homes. We open doors and windows for at least 10 minutes every day. This brings outdoor air inside. Fans and mechanical systems also help move air around.

Using exhaust fans takes out indoor pollutants.

To keep the air clean, we reduce pollutants indoors. Good airflow gets rid of small particles and improves indoor air quality. Making sure homes are well-ventilated supports health by lowering exposure to pollution.

Strategies to Minimize Dampness

To keep homes dry, we aim to maintain humidity levels between 30-50%. This stops mould and mildew from growing. We use exhaust fans in kitchens and bathrooms, open windows for natural airflow, and install mechanical ventilation systems when needed.

Regular cleaning of our heating, ventilation, and air conditioning systems also plays a big part. It’s crucial to ensure that these systems are free from dust and pollutants which can hold moisture.

We make our homes and cars smoke-free zones. Smoke adds to dampness and introduces harmful chemicals into the air. For areas prone to extra moisture, like basements or laundry rooms, we consider using dehumidifiers.

These devices pull excess water from the air, keeping things dry. At iCare Aircon, we’ve seen how proper humidity control can significantly improve indoor air quality and protect your health.

Maintenance of Heating Systems

We always stress the importance of keeping heating systems in top shape. It’s a fact – regular checks and cleanups keep your heater running smoothly and your air quality high. We aim for at least twice-a-year inspections; once before you start using it when the cold hits, and once after to clear any dust or debris that built up.

This means looking at filters, and ducts, and even changing them if they’re too dirty.

In our experience, heaters work best when their parts are clean. This includes the furnace filters which should have a MERV-13 rating for optimal filtering of air pollutants. Check the evaporator coils and condenser unit too; these need to be free from dirt to work efficiently.

If you see signs like short cycling or hear unusual noises coming from your HVAC system, it’s time to call us at iCare Aircon. These could hint at deeper issues such as a refrigerant leak or problems with the power supply needing professional attention right away.

Effective Use of Indoor Plants for Cleaner Air

We choose indoor plants not just for decoration but also to help clean the air. Certain green friends like spider plants, snake plants, and peace lilies can absorb pollutants such as formaldehyde.

These natural air purifiers need little care – just some sunlight and water. Adding a few of these around our home makes a big difference.

Placing these plants in living rooms, bedrooms, and kitchens ensures cleaner air where we spend most time. It’s important to know that while they improve indoor air quality, they don’t replace the need for good ventilation or regular cleaning.

We also make sure to keep the soil healthy and avoid overwatering to prevent mold growth which could harm air quality instead of helping it.

Routine Air Filter Maintenance

We always stress the importance of air filter upkeep. Every 3-6 months, we change these filters to cut down on dust, dirt, and allergens in your home. For folks wanting to trap even tinier particles, we suggest HEPA filters.

These are great at nabbing those small bits that can bother your lungs.

Our team also talks about using furnace filters with a MERV-13 rating for an extra layer of cleaning. Swapping them out regularly ensures nothing nasty gets through your central air conditioning system.

This routine makes sure your living space has cleaner air and keeps your cooling devices working right.

Inspection and Cleaning of Air Ducts

We often find that dust and pollutants build up in air ducts over time. This can harm indoor air quality. Our team at iCare Aircon recommends a thorough inspection and cleaning of these ducts every few years.

Such maintenance ensures the removal of accumulated dirt, improving the flow and quality of air through your home’s heating, ventilation, and air conditioning system.

Changing filters regularly also plays a crucial role here. We suggest swapping out your current ones for high-efficiency particulate air (HEPA) filters every 3-6 months. HEPA filters are great because they catch much smaller particles than standard types do, keeping your home’s ambience cleaner and healthier for you and your family.

Regular Cleaning of Floor Coverings

We always vacuum rugs and carpets to keep our home’s air clean. This removes dust and allergens that can pollute indoor air. We use microfiber or damp cloths for wiping surfaces, avoiding the spread of particles back into the air.

We avoid using heavy chemicals like strong cleaners and air fresheners on floor coverings. These products can harm the quality of our indoor environment. Instead, we choose products that do not release harmful substances into our home’s atmosphere.

Minimize the Use of Scented Products

We know that strong smells from air fresheners and cleaning agents make the inside air worse. Indoor air pollution increases when we use these scented products. Our advice is clear—choose natural cleaners instead.

These options keep the air clean and safe for everyone at home.

Another point—we often open windows to let fresh air in. This helps, but it’s not enough if we’re still spraying chemicals around the house. We suggest exhaust fans or a good ventilation system to move outdoor air in and push indoor pollutants out, especially when you can’t cut down on using some scented items completely.

Aircon Maintenance Advice from Singapore Experts

We always stress the importance of regular air conditioner servicing. Our experts at iCare Aircon recommend checking and replacing air filters every 3-6 months to keep dust, dirt, and allergens away.

This not only improves indoor air quality but also ensures your cooling system runs efficiently. For those in Singapore, battling humidity is a constant; thus, keeping your unit’s condenser coil clean prevents overworking and potential breakdowns.

Servicing your HVAC unit twice a year helps catch problems early. Focus on inspecting refrigerant levels and ensuring there are no leaks in the ductwork. If you own a central air conditioning system, make sure the outdoor unit is clear of debris for optimal performance.

Investing time in routine maintenance avoids major aircon problems down the line.


To wrap it up, clean air at home is not hard to achieve. From cutting down pollutants to using air purifiers and maintaining your A/C, these steps make a big difference. Regular checks on your cooling system keep the air fresh and healthy.
