To stop dust coming through windows, seal air leaks with caulk or weather stripping, keep windows closed on windy days, use fine-mesh screens, and maintain airflow with an HVAC system, while also reducing indoor dust sources like carpets and clutter and cleaning regularly with microfiber cloths and HEPA vacuums.
Window screens with fine mesh: use fiberglass or stainless-steel screens with 18×16 (standard) or 20×20 mesh; for finer dust blocking choose 30×30 or better but expect reduced airflow. Magnetic or snap-on retrofit screens are available for many window types.
A natural dust repellent can be made by combining 1/2 tsp of olive oil, 1 tsp of white vinegar, 1/2 cup of water, 2 drops of dish soap, and 10 drops of lemon essential oil in a spray bottle. Olive oil helps stop dust from collecting on surfaces.
Some things that can reduce the amount of dust are: replace or clean your HVAC filters on their recommended schedules, keep your windows closed (although I would miss the fresh air), use a vacuum cleaner that has a filter, get an air purifier/cleaner appliance for the rooms with the most activity. Good luck!
The cheapest way to seal windows for winter is to apply window film or bubble wrap and seal cracks with weatherstripping and caulking.
I recommend heavy duty clear vinyl on the outside. I have done it the past 2 winters after doing window film on the inside my first winter. It insulates much better (could still feel cold air with window film on inside) and I have no condensation.
Yes, air purifiers can help reduce dust in indoor environments. Air purifiers equipped with High-Efficiency Particulate Air (HEPA) filters are particularly effective at capturing airborne dust particles as small as 0.3 microns with 99.97% efficiency.
All you need is a clean cloth and a cup of tea leaves. Make a cup of tea with your favorite tea leaves first. Allow the tea to cool slightly before straining it with a clean cloth. Rub the cloth over all dust-prone surfaces in your home, such as shelves, baseboards, and windowsills.
The Best DIY Dust Spray You Can Make at Home
In a spray bottle, combine 2 cups of water, ¼ cup white vinegar, 1 tablespoon olive oil, and 3 drops of dish soap (plus, up to 20 drops of scented essential oil for a natural fragrance). Spray onto a microfiber cloth and use it to dust hard surfaces in your home.
Neither vinegar nor Windex is definitively better; they excel at different things: vinegar (acetic acid) cuts grease and mineral deposits for a streak-free finish but may need more wiping and isn't a sanitizer, while Windex (ammonia/alcohol) evaporates quickly for speed but can streak if not wiped thoroughly and may leave residue. Choose vinegar for eco-friendly, tough mineral/grease spots (with soap) or Windex for fast, general cleaning, but always use a microfiber cloth and wipe well for best results with either.
Hotels keep glass shower doors clean using a multi-pronged approach: daily squeegeeing after each use, applying protective hydrophobic coatings, using water softeners to combat hard water, employing commercial cleaners with microfiber cloths or paper towels, and ensuring strict housekeeping routines with post-guest deep cleans. The key is consistent maintenance, not just occasional scrubbing, to prevent soap scum and mineral buildup.
Use an Anti-Static Glass Spray
Anti-static sprays repel dust by neutralizing static electricity that attracts airborne dirt. Regularly applying these sprays keeps interior glass surfaces like mirrors, windows, and tabletops looking freshly cleaned.
Let it sit for 10-20 minutes. The vinegar will help loosen the residue, so you can wipe it away more easily. Bird droppings or other tough grime: pre-soak the area with a vinegar solution and allow it to soften before scrubbing with a damp microfiber cloth.
Golden Rules of Dusting
Work from the top of a room down. This approach allows you to vacuum any dust that settles on the floor. Dust the places you can't see, such as the tops of door frames, ceiling fans, and light bulbs (make sure the lights are off, and the bulbs are cool).
Opt for a HEPA air purifier that captures 99.97% of dust and particles as small as 0.3 microns. Some purifiers also link up to apps on your smartphone to deliver indoor air quality reports. On windy days, keep the windows closed to prevent outdoor particles and allergens from blowing inside and mixing with indoor dust.
Your room may still have dust for several reasons: the air purifier is too small for your room size, filters are clogged and need replacing, the unit is positioned poorly with blocked airflow, or you're not running it continuously.
Air purifier disadvantages include ongoing costs (filters, energy), potential noise, limited effectiveness against gases/odors (unless specialized filters are used), and the risk of ozone production from ionizers, which can harm respiratory health. They also require regular maintenance, can be bulky, and might not purify an entire home effectively, needing multiple units.
Professional cleaners primarily use high-quality microfiber cloths (dry for initial dusting, damp for polishing) and extendable microfiber dusters for high areas, trapping dust effectively due to their fine fibers, along with electrostatic dusters, lambswool dusters, and vacuum attachments, sometimes with dusting sprays for extra shine and dust-repelling power, following a top-to-bottom approach.
Water + Vodka + Olive Oil
Mix together water, vodka and olive oil to quickly create this budget-friendly, natural and effective dusting spray alternative.
All you need to re-create my grandmother's dust-repellant spray recipe is vinegar, olive oil, and a touch of soap. The coating that the spray leaves on surfaces helps prevent dust from adhering and settling in, which means you'll have to clean those hard-to-dust places a little less frequently.
How to Keep Cold Air from Coming Through Windows and Doors
Savings in Energy and Money
Window film covers are inexpensive, reduce drafts, help the house feel warmer during winter months, and reduce moisture buildup on the window due to condensation.
Adding insulation helps regulate the temperature in your building, reduce moisture, and prevent warm, moist air from escaping to cold surfaces where it condenses. Add weatherstripping tape or caulk around windows and doors to seal any air leaks or drafts. This prevents warm, moist air from reaching the cold glass.
