Knowing **how to improve indoor air quality during haze** does not require expensive equipment. A few steady habits can reduce how many particles you breathe and help your space feel fresher. Here are eight practical tips that work for most homes, offices and classrooms in Singapore. ## 1. Keep Windows and Doors Closed Haze particles are tiny, and they come in easily when windows and doors are open. While the PSI is unhealthy, keep them closed as much as you can, and avoid leaving doors open for long periods. Check the latest readings and health advice on the [NEA haze website](https://www.haze.gov.sg), and open windows again only when the air has improved. ## 2. Clean or Replace Air-Conditioning Filters Air-conditioning filters catch dust and fine particles, but only while they are clean. When they are clogged, they hold a lot of dirt and the system has to work harder. A simple step in how to improve indoor air quality during haze is to clean or replace filters more often than usual, and to check that vents are not blocked by furniture or curtains. If you are unsure how to remove or clean your filters safely, ask your air-conditioning technician for help. ![](https://hchcleaning.com.sg/wp-content/uploads/2026/10/improve1.jpg) ## 3. Wipe and Vacuum Instead of Dry Dusting Dry dusting and sweeping send particles back into the air. Use a damp cloth for surfaces, and vacuum floors, carpets and sofas regularly. A vacuum with a good filter is best, since it traps fine dust instead of blowing it out again. For homes, regular [residential cleaning](https://hchcleaning.com.sg/residential-cleaning/) can help keep dust under control when you are busy or when the haze is heavy. ## 4. Use an Air Purifier Wisely An air purifier can reduce particles in a room when it is the right size for the space and its filters are replaced as recommended. Place it where people spend the most time, such as the bedroom or the main work area, and keep doors closed so it can work effectively. Remember that a purifier supports your other steps. It does not replace closed windows, clean filters and regular cleaning. ## 5. Avoid Adding Smoke and Dust Indoors Haze already adds particles to your air, so avoid adding more. Do not smoke indoors, and avoid burning candles, incense or mosquito coils where possible. Be careful with heavy cooking fumes by using the exhaust hood, and keep stacks of paper or boxes tidy, since they collect dust. ## 6. Reduce What Comes In on You Particles cling to hair, clothes, bags and shoes. When you come in from outside, take off your shoes, wash your hands and face, and consider changing clothes if you were outdoors for a long time. In an office, good entrance mats help trap dust before it spreads further. ## 7. Clean Soft Furnishings Carpets, curtains, cushions and sofas trap dust and release it again when they are disturbed. Vacuum them regularly, and wash removable covers and curtains when haze has been heavy. A professional [carpet cleaning service](https://hchcleaning.com.sg/carpet-cleaning/) can remove embedded dust that a household vacuum may miss. ## 8. Measure Instead of Guessing If the air still feels stuffy or people keep complaining, it helps to measure. [Indoor air quality monitoring](https://hchcleaning.com.sg/indoor-air-quality-monitoring/) shows conditions inside your building, such as fine particles, carbon dioxide, temperature and humidity, so you can see what is really happening and decide what to fix. ## Transform Any Space with Expert Cleaning **hCH Cleaning Services** provide comprehensive cleaning solutions for every industry, keeping workspaces, production areas, and common areas spotless and hygienic.

If you have an air purifier, run it in the room where you spend the most time, such as the bedroom at night. **In the office.** Ask building management or your maintenance team about filter cleaning, wipe shared surfaces and meeting-room controls, and keep entrance areas clean. Professional [office cleaning services](https://hchcleaning.com.sg/office-cleaning-services/) can add extra dusting and vacuuming while the haze lasts. **In classrooms and childcare centres.** Children play on the floor and touch many surfaces, so wipe tables, toys and floors with damp cloths and keep rooms closed during unhealthy periods. Regular [preschool cleaning](https://hchcleaning.com.sg/preschool-cleaning/) helps keep shared spaces fresh and hygienic. ## Tips for Each Room at Home Knowing how to improve indoor air quality during haze is easier when you go room by room. **Bedroom.** You spend many hours here, so keep it closed, wash bedding more often and vacuum or wipe surfaces regularly. If you have a purifier, this is a good place for it. **Living room.** Sofas and rugs hold dust. Vacuum them, wash cushion covers and keep windows and balcony doors shut. **Kitchen.** Use the exhaust hood when cooking, and wipe surfaces with a damp cloth. Cooking fumes add particles to the air, so avoid heavy frying on the worst days if you can. **Study or home office.** Keep desks tidy, wipe shared items and make sure the air-conditioning filter is clean. **Entrance and shoe area.** Leave shoes at the door, and wipe bags and umbrellas so dust does not travel through the house. ## How Long Do Particles Stay Indoors? There is no single answer. Particles can stay in the air for hours, and those that settle on surfaces can be lifted again whenever there is movement or airflow. Rooms with clean filters, good sealing and regular cleaning tend to recover faster once the outdoor air improves. That is why cleaning after the haze matters. Damp wiping, vacuuming and filter cleaning remove what has settled, so it does not keep circulating. If you want to know how long it takes in your own space, measuring indoor conditions over time gives a clearer answer. ## What Does Not Help Much Some popular habits give a false sense of safety. - **Spraying air fresheners.** They cover smells but add chemicals, and they do not remove particles. - **Relying on indoor plants.** Plants are nice, but they do not clean the air quickly enough to matter during haze. - **Dry sweeping.** It lifts dust into the air. - **Opening windows briefly to “air out” the room** while the PSI is unhealthy, which lets particles in. - **Using an old, dirty purifier.** A clogged filter does little and can release dust. ## Who Needs Extra Care Children, older adults, pregnant women and people with asthma, heart or lung conditions are more sensitive to haze. If you live with or care for them, pay extra attention to the steps above, keep their rooms clean and follow your doctor’s advice. Schools, childcare centres and care facilities should review their routines too. ## A Simple Routine You Can Follow **Daily:** check the PSI, keep windows closed, wipe surfaces with a damp cloth and vacuum high-traffic areas. **Weekly:** clean or check air-conditioning filters, wash cushion covers and wipe door handles and switches. **After the haze eases:** deep clean carpets and sofas, replace filters, wash curtains and open windows to air the space. ## Quick Checklist: How to Improve Indoor Air Quality During Haze Print or save this list and tick it off each day. - Check the PSI and the NEA advice. - Keep windows and doors closed. - Check air-conditioning filters and vents. - Wipe surfaces with a damp cloth and vacuum floors. - Avoid smoke, candles and incense indoors. - Wash hands and face after coming in. - Run an air purifier in the room where you spend the most time, if you have one. - Note any complaints, odours or dust that returns quickly. If problems continue after you have done these steps, it is time to look deeper at what is happening inside your building. ## Frequently Asked Questions **What is the fastest way to improve indoor air quality during haze?** Close windows and doors, clean air-conditioning filters and switch from dry dusting to damp wiping and vacuuming. These steps cost little and work quickly. **Do I need an air purifier?** Not necessarily. It can help in a room where you spend a lot of time, but the other steps matter just as much. **Is it safe to use the air-conditioning during haze?** Yes, as long as it is well maintained. Clean filters help catch particles, and a dirty system can make indoor air worse. **How do I know if my indoor air has improved?** You may notice less dust, fewer complaints of scratchy throats and fresher-feeling rooms. For a clearer answer, measuring indoor air gives you actual readings. **Can I still ventilate my home during haze?** Wait until the PSI returns to the good or moderate range, then open windows to air the space. If you need to ventilate sooner, keep it brief and follow official advice. **Is there one step on how to improve indoor air quality during haze that matters most?** Keeping outdoor air out and keeping your air-conditioning filters clean are the two steps that make the biggest difference for most buildings. ## Final Thoughts Knowing how to improve indoor air quality during haze comes down to a few reliable habits: keep particles out, clean what gets in, look after your filters and measure when you are unsure.
