How to Purify Air Naturally at Home Using Simple Methods

The air inside your house might not be as safe as you believe and the cost of ignoring the indoor air quality is often paid for with health issues.. Indoor air can become toxic due to several reasons, including dust, smoke, cooking fumes, pet dander, and outdoor pollution entering homes, so it’s important to know how to purify air naturally at home to protect your health. 

Before we discuss how can we keep the air clean naturally, let’s see some common causes of poor indoor air quality.

What Causes Poor Indoor Air Quality? 

Reasons for poor indoor air quality can depend on your home’s design, habits, and surroundings. Understanding why air becomes polluted is important to find the best solutions to tackle it. 

Everyday Factors That Degrade Indoor Air

Several everyday items and conditions inside your home can release harmful particles and chemicals. Identifying these indoor sources is essential for improving air quality and creating a safer, healthier living environment.

• Tobacco Smoke: Releases particulate matter and toxic chemicals that linger indoors, affecting lung health.

  
  

• Low-Quality Building Materials & Paints: Off-gassing volatile organic compounds (VOCs) such as formaldehyde degrade indoor air. 

  
  

• Dampness & Mould: Moisture accumulation promotes mould growth and dust mites, contributing to allergens and respiratory irritants.

  
  

How Indoor Cooking Fuels Affect Air Quality

Many Indian households still use wood, coal, crop residue, or dung for cooking or heating. Incomplete combustion of these fuels releases harmful pollutants, including fine particulate matter and carbon monoxide, which can severely affect indoor air quality.

• Particulate Matter (PM2.5 & PM10): Fine dust from burning solid fuels penetrates deep into the lungs, causing respiratory issues. 

  
  

• Carbon Monoxide (CO): Colorless, odorless gas produced during incomplete combustion can cause headaches, dizziness, and long-term health risks.

How to Purify Air Naturally at Home: 10 Effective Methods

These natural methods can be effective in improving indoor air quality. From houseplants to ventilation and natural filters, these ten proven ways can significantly improve air quality in Indian homes.

Ventilation and fresh air exchange

This might sound like a no-brainer but, improving ventilation helps dilute indoor pollutants and bring in fresh air, reducing dust, smoke, and VOCs. Open windows on opposite sides of rooms to create cross-ventilation for at least 15–30 minutes daily, and use exhaust fans in kitchens and bathrooms. Regularly doing this can significantly lower indoor pollutant levels and maintain healthier air.

Place air‑purifying houseplants in your house

Air purifying plants are effective natural air purifiers because they absorb pollutants like VOCs, formaldehyde, and dust while releasing oxygen. Placing them in bedrooms, living rooms, or near windows can make a noticeable difference in fresher, healthier air.

Best indoor air-purifying plants for Indian homes:

• Snake Plant (Sansevieria trifasciata) – survives low light, absorbs toxins.

  
  

• Aloe Vera – filters chemicals and releases oxygen at night.

  
  

• Peace Lily (Spathiphyllum) – removes VOCs and mould spores.

  
  

• Areca Palm (Dypsis lutescens) – humidifies air while filtering pollutants.

  
  

• Spider Plant (Chlorophytum comosum) – hardy plant, effective at removing formaldehyde.

  
  

Avoid Smoking and Burning Incense Indoors

Smoke from cigarettes, incense, and candles releases particulate matter and harmful chemicals that degrade indoor air quality. Limiting or avoiding these sources prevents respiratory irritation and reduces VOCs in the home. If you must use incense or candles, do so in well-ventilated areas, for short periods, and away from bedrooms or children.

Use Exhaust Fans and Chimneys to Remove Indoor Pollutants

Exhaust fans and kitchen chimneys effectively remove smoke, cooking fumes, and humidity, preventing indoor pollutants and mould build-up. Install a chimney above the stove to capture grease and fumes. Run fans during and after cooking or to maintain healthier indoor air.

Maintain a Dust-Free Home with Regular Cleaning

Regular cleaning is one of the most effective ways to reduce indoor air pollutants like dust, pet dander, and allergens. Use a vacuum cleaner with a HEPA filter for carpets and rugs, mop floors regularly, and wipe surfaces with damp cloths to trap dust rather than spreading it. Minimizing clutter reduces surfaces where dust accumulates, keeping air cleaner and healthier for breathing.

Keep Outdoor Pollutants Out with a Shoes-Off Policy

Shoes can carry dust, pollen, bacteria, and other pollutants from outside into your home, which can settle on floors and become airborne, affecting indoor air quality. Adopting a shoes-off policy at the entrance and using designated indoor footwear or slippers prevents these contaminants from spreading. This simple habit reduces allergens, keeps floors cleaner, and helps maintain fresher, healthier air inside your home.

Keep Your Pets Groomed to Reduce Indoor Allergens

Pet dander, found in fur, skin, and saliva, is a major source of indoor allergens and can affect air quality, especially for sensitive individuals. Regularly bathing, brushing, and grooming pets minimizes the spread of dander throughout the home. Additionally, keeping pet bedding clean and vacuuming areas where pets spend time can further reduce allergens, helping maintain healthier, fresher indoor air.

Use Non-Toxic Cleaners to Improve Indoor Air

Many conventional cleaning products release volatile organic compounds (VOCs) that can irritate eyes, throat, and lungs and reduce indoor air quality. Using non-toxic or green cleaning alternatives like vinegar, baking soda, citrus juice, or essential oils reduces these pollutants. You can make your own cleaners or purchase eco-friendly brands. Always ventilate while cleaning to maintain fresh and healthy air.

Use Charcoal Bags as Natural Air Purifier

Activated charcoal and bamboo charcoal are highly porous materials that can trap moisture, odours, and volatile organic compounds in your home. Placing charcoal bags in closets, under beds, or near windows helps absorb pollutants and reduces stale smells naturally. Refresh or sun-dry the bags every 1–2 months to maintain effectiveness. This natural air purifier supports healthier indoor air and a fresher living environment.

Install an Air Purifier to Combat Indoor Pollution

When natural solutions aren’t enough, investing in a good air purifier can make a noticeable difference, especially in Indian cities with high pollution levels. A purifier with a HEPA filter captures fine dust and allergens, while a carbon filter reduces odours and VOCs. Keep it in living areas or bedrooms and run it during peak smog or dust days for cleaner, healthier indoor air. 

Creating a Healthier Home with Cleaner Air

Maintaining clean indoor air is essential for a healthy home, and combining natural methods with smart practices can make a real difference. Simple steps like proper ventilation, air-purifying plants, dust control, and pet grooming, along with natural cleaners and charcoal bags, go a long way. In areas with high pollution, an air purifier can provide extra protection. By adopting these strategies, you can create a fresher, safer living environment and enjoy cleaner air every day.
