- •Shoes bring in a lot of outside dirt and dust, so placing doormats and removing shoes outside helps reduce indoor dust.
- •Regularly grooming pets, cleaning their paws, and washing their bedding prevents dust and dander accumulation.

- •Using microfiber cloths, cleaning AC filters, and vacuuming with HEPA filters effectively keeps indoor dust under control.

Even when doors and windows are shut, dust and air can enter through small cracks and gaps in their frames and walls. Additionally, outdoor dirt and particles cling to the soles of shoes, and dust is brought inside via clothes, pets, and gaps.
You can check the areas around your doors and windows for any gaps or cracks. Sealing these openings using weather stripping or a suitable sealant helps reduce the amount of dust entering from outside.
Road dust and dirt stick to the soles of shoes from outside, making it important to use doormats and clean shoes immediately upon entering. For pets, cleaning their paws when coming from outside, grooming them regularly, and keeping their bedding clean helps manage dust.
