7 Tips to Improve Your Home’s Air Quality

Tips to Improve Your Home’s Air Quality

Here are seven tips to help you achieve cleaner and fresher indoor air:

1. Maintain HVAC Systems

HVAC filters should be replaced every 1-3 months, with high-efficiency filters such as MERV 13 or higher recommended for better filtration. Additionally, it is important to have your heating, ventilation, and air conditioning systems inspected and cleaned annually by a professional.

This ensures that the systems are running efficiently and not circulating contaminants. Professional duct cleaning every few years can also help, especially if there is noticeable dust buildup, mold, or evidence of pests in the ducts. This can further improve air quality by removing accumulated debris and allergens from the ductwork.

2. Ventilate Regularly

Ensuring proper ventilation is crucial. Natural ventilation involves opening windows and doors for at least 15-20 minutes daily, regardless of the season. This practice helps to expel stale air and replace it with fresh outdoor air, reducing the concentration of indoor pollutants and moisture levels.

For homes with limited window access, exhaust fans in kitchens and bathrooms are essential. These fans should be used during and after activities that generate steam, such as cooking or showering, to remove excess moisture and prevent the buildup of mold and mildew.

Cross-ventilation can be achieved by opening windows on opposite sides of the house to create a breeze that helps to distribute fresh air throughout the space.

3. Use Air Purifiers

Air purifiers are another vital component in improving indoor air quality. High-Efficiency Particulate Air (HEPA) filters are particularly effective, capable of capturing 99.97% of particles as small as 0.3 microns, including dust, pollen, pet dander, and other allergens.

To maximize their effectiveness, air purifiers should be placed in the most frequently used rooms, such as bedrooms and living areas, and positioned so that they are not obstructed by furniture.

Regular maintenance is key; filters should be changed according to the manufacturer’s recommendations, typically every 6-12 months, to ensure they continue to function efficiently.

4. Control Humidity Levels

High humidity can promote the growth of mold and dust mites, while low humidity can cause respiratory discomfort. To maintain optimal humidity levels between 30% and 50%, use dehumidifiers in damp areas like basements and bathrooms.

This helps to prevent mold growth and reduces the prevalence of dust mites. In drier climates or during winter, humidifiers can help maintain comfortable humidity levels.

However, it is important not to over-humidify, as this can also lead to mold and mildew issues. Monitoring indoor humidity with a hygrometer can help you adjust your dehumidifier or humidifier settings accordingly to maintain a balanced environment.

5. Choose Low-VOC Products

Choosing low-VOC (volatile organic compounds) products is another effective strategy for improving indoor air quality. VOCs are harmful chemicals that can off-gas from various household products, including paints, varnishes, cleaning supplies, and furniture.

Opt for low-VOC or zero-VOC paints and finishes when renovating or redecorating. These products emit fewer harmful chemicals, making them safer for indoor use. For cleaning supplies, look for environmentally friendly, non-toxic options, often labeled with certifications such as “Green Seal” or “EPA Safer Choice.”

When purchasing new furniture, consider items made from natural materials or those certified by programs like GREENGUARD, which ensures low chemical emissions, thereby reducing the number of VOCs in your home.

6. Clean Regularly

Dust surfaces with a damp cloth to trap particles instead of just moving them around. Pay special attention to areas that accumulate dust, such as shelves, blinds, and ceiling fans.

Use a vacuum cleaner with a HEPA filter to effectively capture fine particles and vacuum carpets, rugs, and upholstery at least once a week. Regular washing of bedding, pillowcases, and curtains in hot water helps eliminate dust mites and other allergens.

Consider using allergen-proof covers for pillows and mattresses to further reduce allergen exposure, creating a cleaner and healthier sleeping environment.

7. Introduce Indoor Plants

Certain plants, such as spider plants, peace lilies, and snake plants, are known for their ability to absorb toxins like formaldehyde, benzene, and trichloroethylene from the air while releasing oxygen.

Place these plants in well-lit areas and care for them according to their specific needs, being mindful not to overwater them to avoid mold growth. While plants can be beneficial, it is important to be aware of any potential allergies.

Choose hypoallergenic plant varieties if allergies are a concern, and ensure plants are kept clean and free of dust to maximize their air-purifying benefits.
