The 7-Day Smog-Proof Home Reset: Windows, Cooking, Shoes, Sleep
Doing this reset? Tick off each day as you go. Progress stays on this device; missed days are fine.
You finished all seven days. That's the habit part done; keep the pieces that suited you.
First, the one rule that outranks everything else here: a room sealed against smog with a gas heater running can kill, because carbon monoxide builds up with no smell. Ventilate for the heater, even on the worst smog day. With that settled, this 7-day home reset makes the air in your house cleaner without buying anything big: a window schedule, a shoes-off door, a smoke-free kitchen, and a bedroom that lets you sleep.
Never sleep in a closed room with a gas heater, angeethi, coal or wood fire burning. Headache, dizziness, nausea or drowsiness that improves in fresh air can be carbon monoxide poisoning: switch off the heater, open doors, get everyone out and seek emergency care. The full heater guide is in winter heaters and carbon monoxide. Separately, anyone with wheeze, a tight chest, fast breathing or blue lips needs their asthma plan and a doctor, whatever the house looks like. A cleaner home eases symptoms; it doesn’t replace care.
What this reset can and can’t do
Most of the smog in a house comes in through gaps and open doors, on shoes and clothes, and from things we burn inside: frying oil, incense, mosquito coils, cigarettes. You can’t make indoor air as clean as a mountain. You can take away the sources you control and keep outdoor smog out during its worst hours. The deeper why is in indoor air pollution at home.
Day 1 is deliberately easy. Each day adds one habit. Miss a day and just carry on from where you stopped; nothing resets to zero.

Day 1: Find your worst hours and set a window schedule
Open any air-quality app and pick the sensor nearest your home. Check it at 7 am, 1 pm and 9 pm today. In most Punjab winters, nights and early mornings are worst because cold air traps smoke near the ground, and early afternoon is best.
- Shut windows by sunset and keep them shut until late morning.
- Open two windows on opposite sides for 10 to 15 minutes around 12 to 2 pm, when readings usually dip. A cross breeze swaps the stale air quickly.
- Keep a small gap open in any room with a gas heater, always.
Day 2: Shoes off at the door and a wet-mop routine
Street dust rides in on soles. Put a coarse doormat outside and a second one inside, with a rack for shoes by the door. Chappals for indoors only.
Dry sweeping with a jharu throws the fine dust back into the air you breathe. Switch to damp: a cloth wrung out in plain water for surfaces, and a wet mop for floors. A bucket of about 5 litres of water with a capful of floor cleaner does a whole flat. Mop daily on smog weeks, starting from the far room and working towards the door.
Day 3: The smoke-free kitchen
Frying at high heat can fill a closed kitchen with more fine particles than the street outside.
- Switch the exhaust fan on before the pan heats, and leave it running 10 minutes after.
- Don’t fry with the kitchen door shut and windows sealed; open the kitchen window a crack while cooking, even on smog days.
- Lids on pans, lower flames, and fewer deep-fried dishes on red-alert days.
- Throw out incense, dhoop and mosquito coils for the season. Plug-in or net options make far less smoke.
- No smoking indoors, including “just by the window”.
The cheapest air cleaner in the house is the pan lid.
Day 4: A mask hook and a rinse station by the door
Screw a hook beside the front door for each person’s mask, with a paper bag for spares. Masks go on at the door and come off at the door, so nobody hunts for one at 7 am.
Next to it, a small rinse station: soap by the nearest tap, a clean towel, and a jug of cooled boiled water for anyone whose eyes sting after the commute. Wash face and hands on arrival. It takes a minute and keeps the dust off pillows.
Day 5: The bedroom
You spend a third of the day here, so this is the room to guard.
- Wipe the window sill, headboard and fan blades with a damp cloth. Fan blades collect a thick grey layer that spins back down.
- Shake out and change pillowcases twice a week on bad weeks.
- Keep the bedroom door shut in the evening so kitchen and street smoke stay out.
- Heaters dry the air: a bowl of water in the room or a line of drying laundry adds some moisture. Switch gas heaters off before sleep.
- No smoking in the bedroom, ever.
Day 6: The DIY box-fan filter, honestly
People search “air purifier kaise banaye” every November. The home version is a box or pedestal fan with a flat furnace-style filter strapped to its back, so the fan pulls room air through the filter. Filters rated MERV 13 or better catch a fair share of fine particles.
What it can do: lower dust in one closed room, especially a bedroom. What it can’t: clean a whole house, run safely unwatched overnight if the motor overheats, or match a proper purifier sized for the room. Keep it at least a metre from curtains, never leave it running while you’re out, and change the filter when it turns grey. Plants won’t do the job either; the honest verdict is in air-purifying plants in smog season.
Day 7: The family plan for red-alert days
Write it on one sheet of paper and stick it on the fridge.
| When | What to do |
|---|---|
| Morning | Check the reading; windows stay shut; masks on at the door |
| Midday | Air the house 10 to 15 minutes; outdoor errands now |
| Evening | Windows shut by sunset; exhaust on for cooking; no frying marathons |
| Weekly | Wipe fan blades and sills; wash doormats; check masks and filters |
| Monthly | Check exhaust fan grease; replace a grey DIY filter |
Add names: who has asthma and where the inhaler is kept, who is elderly or pregnant, which child stays home above which reading. Put the doctor’s number on the same sheet.
The busy person’s version
If you do only three things: shut windows at sunset and air at midday, shoes off at the door, and exhaust on whenever the stove is lit. Those three carry most of the benefit. Everything else is a bonus when you have the time.
What to expect after a week
Be modest. Families usually notice less grey grit on sills and floors, fewer morning coughs and stuffy noses, and less eye-rubbing after the school run. Nobody’s lungs become “clean” in seven days, and outdoor smog still matters. If someone is still wheezing or coughing at night, that’s a doctor’s question, not a cleaning one. More resets live in The 7-Day Reset.
Many homes burn loban or dhoop to “clean” the air in winter. It smells like care, but it adds the same fine smoke you’re keeping out. Keep it for another season, or for outdoors.
Smog-proof home questions
How do you reduce smog inside the house?
Shut windows in the evening, night and early morning, air the house briefly at midday, take shoes off at the door, damp-mop instead of sweeping, and cut indoor smoke from frying, incense and cigarettes.
Should windows be kept closed all day during smog?
Not all day. Close them during the worst hours and air the house for 10 to 15 minutes at midday. Rooms with gas heaters always need some fresh air.
Is a gas heater safe with windows closed in smog?
No. A gas heater in a sealed room can build up carbon monoxide, which can kill without warning. Keep a gap open and switch it off before sleeping.
How to make an air purifier at home (air purifier kaise banaye)?
Strap a MERV 13 or better furnace-style filter to the back of a box fan so it pulls air through. It helps in one closed room; it isn’t a match for a proper purifier and shouldn’t run unwatched.
Does mopping really reduce indoor dust?
Yes, damp mopping and wiping trap fine dust, while dry sweeping throws it back into the air. Daily damp cleaning on smog weeks makes a visible difference to surfaces.
What are the health effects of smog indoors?
The same as outdoors, only milder when the house is managed well: coughs, sore throats, stinging eyes and asthma flares. Indoor smoke sources make it worse.
Do indoor plants clean smog from the air?
Not in any amount you’d notice in a real room. Keep plants for their beauty and put your effort into windows, cooking smoke and cleaning.
Is it safe to burn incense or dhoop in smog season?
Better not. Incense and dhoop give off fine smoke indoors, which is what the smog season already brings. Skip them, especially near children and anyone with asthma.
What if a day of the reset gets missed?
Just carry on from the next day. Each habit stands alone, and the busy version (windows, shoes, exhaust fan) keeps most of the benefit.
How can you check if indoor air is better?
Look for less grit on sills and fan blades, fewer morning coughs and less eye-rubbing. A low-cost home sensor shows the trend but reads roughly, especially in humid air.
