When you think about air pollution, you probably picture busy roads and traffic fumes. However, studies show that the air inside our homes can often be more polluted than the air outside.
Dust, pet hair, cooking smoke, and the VOCs released by cleaning products all build up over time. These can affect your sleep, your focus, and your overall health, especially if you have allergies or asthma.
If you want to create a healthier living environment, you’re in the right place. This guide shares simple, practical tips on how to improve air quality in home. You’ll learn easy changes that help clear the air and make your home feel fresher for you and your family.
Improve Ventilation
Good ventilation is one of the simplest ways to clean air at home. It pushes stale air out and brings fresher air in. Various guidance stresses that steady airflow helps keep pollutants, moisture, and even viruses at lower levels.
Small habits make a big difference, whether you live in a house or a small flat. Here’s what to do:
Open Windows and Doors
The easiest step is to use your windows and doors. When you open windows on opposite sides of your home, you create cross-ventilation that carries out moisture, cooking fumes, and other indoor pollutants.
You don’t need them open for long. Short bursts—about 10 to 15 minutes a few times a day—refresh the air without losing too much heat. This helps most after cooking, showering, or using strong cleaning sprays.
Try these simple habits:
- Open windows slightly in different rooms to set up a gentle through-draft when the outdoor air is cleaner.
- Choose quieter times of day, like late evening on busy streets, to reduce traffic fumes coming in.
- Keep interior doors open so fresh air can move through your home more evenly.
- Pair open windows with a fan pointing outward to pull stale air out faster.
Use Exhaust Fans
Extraction is especially important in the rooms that create the most steam and fumes. Kitchens and bathrooms top the list. Cooking, boiling water, and hot showers all release moisture and tiny particles that can lead to damp, mould, and breathing issues.
Many homes already have extractor fans, but they’re often switched off too soon or left unmaintained.
To get the most out of them:
- Run your kitchen extractor while cooking and keep it on for at least 10–15 minutes afterwards to clear smoke and grease.
- Use the bathroom fan during your shower and leave it running for around 30 minutes to remove condensation.
- Check that your fans vent outdoors rather than recirculate air back into the room.
- Clean fan covers and filters so the system can move enough air to prevent damp and odours.
Keep Vents Clear
Your home’s built-in vents also help keep air moving. Trickle vents, wall vents, and air bricks all limit condensation and reduce indoor pollutants, especially in modern, tightly sealed homes.
But they only work when they’re clear. Furniture, blinds, and dust can block airflow without you noticing.
A few simple checks help keep them working:
- Leave a small gap between furniture and wall vents or radiators so air can pass through.
- Avoid sealing trickle vents or air bricks, even in winter when you want fewer draughts.
- Dust or vacuum vents gently to stop debris from settling and blocking airflow.
- Check any filters or grilles on mechanical ventilation systems and clean or replace them as advised.
Cut Down Indoor Pollution
Once you’ve improved airflow, turn to the sources of pollution inside your home. Reducing smoke, harsh chemicals, and excess dust gives you a cleaner baseline to work with. It also means your ventilation and filters don’t have to work as hard.
Avoid Smoking
Tobacco smoke is one of the biggest contributors to poor indoor air. Smoking indoors releases fine particles and toxic gases that cling to carpets, curtains, and furniture.
Even smoking near a window doesn’t stop these residues from settling. They can trigger asthma, irritate your lungs, and raise long-term health risks for everyone in the home, including children and pets.
A few simple rules help:
- Keep a strict smoke‑free rule inside your home and car to protect indoor air.
- Ask guests to smoke outside and well away from doors or windows.
- Limit incense and scented candles, which also produce fine particles and chemicals.
- Seek NHS support if anyone in your household wants help cutting down or quitting.
Limit Chemicals
Everyday products play a bigger role in indoor air than most people expect. Many cleaners, sprays, and fragrances release volatile organic compounds (VOCs), which can irritate your eyes and airways, especially if you have allergies or asthma. These chemicals build up quickly in well-sealed homes that don’t get much fresh air.
To cut down on exposure:
- Choose fragrance-free or low-VOC products when you can.
- Use trigger sprays instead of aerosols and spray them onto cloths, not into the air.
- Go easy on air fresheners; open windows to clear smells when possible.
- Store paints, solvents, and DIY chemicals in sheds or well-ventilated spots, not in living spaces.
Clean Regularly
Good cleaning habits help manage dust, pet dander, and other tiny particles that float into the air. These settle on floors and soft furnishings, then rise again whenever someone sits down, walks past, or shakes out curtains.
Regular vacuuming, damp dusting, and washing textiles make a big difference, especially if anyone has asthma or allergies.
A few helpful routines include:
- Vacuuming floors, rugs, and upholstery once or twice a week, using a machine with strong filtration.
- Washing bedding at 60°C frequently when the care label allows, which helps remove dust mites and their droppings.
- Using a damp microfiber cloth instead of dry dusters so particles stick to the cloth rather than floating into the air.
- Reducing clutter so dust has fewer places to hide.
If you struggle to keep up with the hoovering, a robot vacuum can take care of the day-to-day dust and crumbs for you. You still do the occasional deep clean, but the robot keeps on top of the background mess so less ends up in the air.
Here’s how a few eufy models can support cleaner indoor air in different ways:
eufy Robot Vacuum E20
The eufy Robot Vacuum E20 is a 3-in-1 model that works as a robot, a stick vacuum, and a handheld. It uses strong suction — up to 30,000 Pa in stick/handheld mode and 8,000 Pa in robot mode — which helps pull fine dust out of carpets, sofas, and corners.
A five-stage AeroTurbo™ filtration system is designed to capture up to 99.7% of particles as small as 0.3 microns, including pollen and dust-mite debris. That means less of that fine material ends up blowing back into the room. The auto-empty station stores up to about 75 days of dust, so you’re not opening the bin all the time.
If you want one machine that cleans floors on its own but can also convert for stairs or upholstery, the E20 does a bit of everything.
eufy X10 Pro Omni
The eufy X10 Pro Omni offers 8,000 Pa of suction for carpets and pet hair, plus a dual-mop system that scrubs hard floors at 180 rpm. The mop lifts by 12 mm when it reaches carpet, so rugs stay dry.
Its AI.See™ camera system helps the robot avoid common obstacles like shoes and cables, which keeps the cleaning routine smooth. The all-in-one base empties dust, washes the mop pads, and dries them with warm air to stop them going musty.
If you want a simple way to vacuum and mop without managing lots of settings, the X10 Pro Omni is an easy daily helper.
eufy Robot Vacuum Omni S1 Pro
The eufy Robot Vacuum Omni S1 Pro combines 8,000 Pa suction with a square shape that reaches corners more effectively. Its Always Clean Mop™ rinses and cleans itself continuously using a dual-tank system, so you’re mopping with fresh water instead of spreading dirty water around.
It can also make ozonated water, which lab tests show can remove up to 99.99% of certain bacteria and fungi on hard floors. The mop lifts for carpets, and the base station handles emptying, washing, and hot-air drying automatically.
This model suits homes that want strong cleaning with less hands-on work and a bit more focus on hygiene.
eufy Robot Vacuum Omni S2
The eufy Robot Vacuum Omni S2 is designed for deeper carpet cleaning. Its AeroTurbo™ system can reach up to 30,000 Pa and around 100 AW of suction, which helps pull dust out of deeper carpet fibres.
For mopping, the HydroJet™ system uses a self-rinsing roller with 32 water injection holes and ozonated water that can remove up to 99.99% of germs in lab tests. Its CleanMind AI and 3D MatrixEye™ 2.0 sensors help it identify obstacles and adjust how it cleans.
The UniClean™ station handles dust emptying, mop washing, detergent dispensing, and heated drying on its own, so the robot can manage long stretches without much input.
If you want strong carpet extraction and hands-free maintenance, the S2 is the most automated option.
Check Heating Systems
Heating systems also affect indoor air. Poorly maintained boilers, fires, or heaters can release carbon monoxide and other harmful gases. Blocked flues make risks even higher. Regular servicing is important in the UK, where heating runs for long stretches through autumn and winter.
Keep things safe by:
- Having gas boilers, fires, and flues serviced once a year by a Gas Safe registered engineer.
- Installing and testing carbon monoxide alarms in rooms with fuel-burning appliances.
- Making sure vents and air bricks near heaters aren’t blocked by furniture, dust, or DIY work.
- Never using outdoor items such as barbecues or petrol heaters inside enclosed spaces.
Add Indoor Plants
Of course, you can use indoor plants to clean the air. They won’t replace good ventilation or filtration, but they can make a room feel fresher and may help balance humidity. It’s worth choosing plants that won’t add to pollen or mould problems, especially if someone in your home is sensitive.
A few tips to keep them helpful:
- Pick low-pollen, easy-care species, like snake plants or spider plants, and avoid overwatering to prevent mould in the soil.
- Keep plants out of bedrooms if anyone has pollen or mould allergies.
- Use plants as a complement to other air-quality measures, not a replacement.
- Dust the leaves now and then so they don’t collect particles.
Use Air Filters and Purifiers
Once the basics are in place, the next step is improving how your home filters the air.
Heating systems, ventilation units, and standalone purifiers can all help capture dust, pollen, and smoke. They’re especially helpful if you live near busy roads or share your home with someone who has allergies.
These tools don’t replace good cleaning or ventilation; they work alongside them to keep indoor air fresher.
Change HVAC Filters
If your heating or ventilation system has filters, keeping them clean is important. Even though many UK homes use radiators rather than full HVAC systems, some boilers and ventilation units still rely on filters to protect the equipment and keep air moving smoothly. When these filters clog, they lose efficiency and may push dust back into the room.
A few simple habits help:
- Check your system’s manual for how often to inspect or change the filter.
- Look over filters at the start and end of the heating season.
- Use the best-quality filter your system can handle without blocking airflow.
- Ask your engineer which filter type suits your home and any allergy needs.
Consider Air Purifiers
Air purifiers can help in rooms where dust, traffic fumes, or allergens build up easily. Models with true HEPA filters catch tiny particles such as pollen, pet dander, and fine dust. They work best when you use them alongside regular cleaning and good ventilation, not in place of it. Bedrooms and living rooms near busy streets can benefit the most.
When choosing and using a purifier:
- Pick a model with a true HEPA filter and a Clean Air Delivery Rate that matches your room size.
- Run it on a low, steady setting while the room is in use.
- Keep it away from walls and furniture so air can move through it freely.
- Replace HEPA and pre-filters as recommended to keep performance high.
Control Moisture and Damp
Managing indoor moisture is essential for both comfort and health. High humidity, damp areas, and mould can irritate lungs and trigger asthma or allergies. Dust mites also thrive in damp environments. Keeping humidity balanced and fixing damp sources helps protect indoor air and the building itself.
Use a Dehumidifier
A dehumidifier can help bring moisture down to a healthier level. Lower humidity makes it harder for mould and mites to grow, and it reduces the chance of condensation forming on windows and walls.
A few pointers:
- Use a dehumidifier in rooms that often show condensation, such as bedrooms or bathrooms.
- Aim for indoor humidity of 40–60%, checked with a simple hygrometer.
- Empty and clean the water tank often so mould and bacteria don’t grow inside.
- Pair the dehumidifier with ventilation and gentle heating so surfaces can dry fully.
Fix Leaks
Many damp problems start with water coming from the wrong place: leaky roofs, damaged pipes, blocked gutters, or poorly sealed windows.
These can leave damp patches that encourage mould and damage walls and woodwork. If you rent, your landlord is responsible for repairing serious leaks and mould once they’re reported.
Useful steps include:
- Look for stains, flaking paint, or musty smells near ceilings, skirting boards, and outside walls.
- Report leaks promptly if you rent, and keep a written record of conversations or emails.
- Clear gutters and downpipes when safe, or arrange for professional help.
- After repairs, dry the area fully to stop mould from returning.
Conclusion
Improving your indoor air doesn’t have to be complicated. When you focus on ventilation, reduce pollution at the source, clean regularly, and manage moisture, you create a healthier space day by day. Using filters, purifiers, and simple habits together gives you the best results. With these steps, you now know how to improve air quality in home settings in a way that’s practical, sustainable, and easy to maintain. Small changes add up, and the payoff is a home that feels fresher, cleaner, and more comfortable for everyone.
