Change Your HVAC Filters Regularly
Keeping the air in your home clean is key for your family’s health and comfort. Changing your HVAC filters often is a simple way to do this. These filters catch dust, pollen, pet dander, and more as air moves through your home.
Importance of Changing HVAC Filters
Not changing your HVAC filters can cause problems. Dirty filters make your system work harder, which uses more energy and raises your bills. They also fill your home with pollutants, which can make breathing hard and cause health issues.
Types of HVAC Filters
- Fiberglass filters: These basic filters have a MERV (Minimum Efficiency Reporting Value) rating of 4, capturing larger particles but allowing smaller ones to pass through.
- Pleated filters: With a MERV rating between 5 and 8, pleated filters offer better filtration performance than fiberglass, trapping smaller particles.
- HEPA (High-Efficiency Particulate Air) filters: These high-performance filters have a MERV rating of 11 or higher, capable of capturing up to 99.97% of particles as small as 0.3 microns.
Frequency of Filter Changes
How often you should change your HVAC filters depends on a few things. This includes the filter type, your home’s size, and if you have pets or other factors. Here’s a basic guide:
- Fiberglass filters should be replaced every 30 days.
- Pleated filters should be changed every 2-3 months.
- HEPA filters may last 6-12 months before needing replacement.
If you have pets, smoke, or allergies, you might need to change your filters more often. Up to every 20-30 days is recommended. Checking your filters often can also tell you when it’s time for a change.
Regularly changing your HVAC filters keeps your air system running well and your air clean. This easy step can greatly improve your home’s air quality and comfort.
Check and Clean Other Household Filters
HVAC filters are key to clean air inside your home. But, other filters like vacuum cleaners, clothes dryers, and kitchen vents also need cleaning. Keeping these filters clean helps improve the air quality you breathe daily.
Vacuum Cleaner Filters
Vacuum filters catch dust, pet hair, and other particles to keep the air clean. Clean or replace them every few months for best results. If you ignore them, your vacuum won’t work well and may spread pollutants around.
Clothing Dryer Filters
Don’t forget about your dryer’s lint filter. Lint and fibers from clothes can clog it, making the dryer less efficient and even dangerous. Clean it after each use to keep your air and home safe.
Kitchen Vent Filters
Kitchen vent filters catch grease, smoke, and smells from cooking. Clean or replace them often to keep the air fresh. If you don’t, pollutants can build up, harming your air quality.
Regularly checking and cleaning these filters helps trap indoor pollutants. This simple step, along with other actions, can make your home healthier.
“Maintaining household filters is a crucial but often overlooked aspect of indoor air quality management. Regular filter cleaning and replacement can make a significant difference in the air we breathe at home.”
Inspect and Maintain Air Ducts
Your home’s air ducts are key to moving heated and cooled air around. Over time, they can fill up with dust, dander, and mold. This can hurt your indoor air quality (IAQ). Not checking and maintaining your ducts can cause bad air flow, more breathing problems, and a less efficient HVAC system.
Getting a professional to check your ducts often can spot contaminants or issues. The ACR Standard says to look for dust, debris, mold, and other problems. This matches what the National Air Duct Cleaners Association (NADCA) suggests for good IAQ.
If there are contaminants, you might need a deep clean. Using HEPA vacuums and special brushes can get rid of dust, allergens, and mold. This makes the air in your home better and can save energy.
Changing air filters often is also key. Good filters catch particles before they get into the ducts. Sealing leaks in the ducts stops contaminants from getting in and keeps air flowing well.
Being proactive with air duct inspection and maintenance keeps your home healthy and efficient. Getting professional duct cleaning and regular care helps your breathing, HVAC system, and air quality.
“Proper ventilation, represented by the ‘V’ in HVAC systems, plays a crucial role in maintaining high indoor air quality (IAQ) and a healthy living environment.”
Use Cooking Vents and Open Windows
Keeping the air in your kitchen clean is key. Cooking, especially with gas stoves, can release harmful gases like carbon monoxide and nitrogen dioxide. Using your kitchen vents or opening windows helps filter out these pollutants.
Importance of Ventilation
Homes with gas stoves often have more nitrogen dioxide (NO2) than those with electric stoves. These pollutants can cause health problems like nose and throat irritation, headaches, fatigue, and nausea. So, it’s important to have good ventilation while cooking.
Proper Use of Cooking Vents
Clean your kitchen vents every 1-2 months if you cook often, or once a year if you cook less. A high-efficiency range hood that vents outside is best for kitchen ventilation. Also, have a pro check your gas stove yearly for leaks and carbon monoxide.
If you don’t have a range hood, use wall or ceiling exhaust fans during cooking. Opening windows and doors can also help improve air flow in the kitchen.
“Proper ventilation should be a part of the cooking process. Recommendations include keeping the cooking area clean of grease and food residue, using ventilation before and after cooking, opening windows during cooking, and matching ventilation settings to the cooking style, burner size, and cookware.”
Following these simple steps can greatly improve your indoor air quality. This makes your home a healthier place to cook.
Control Indoor Humidity Levels
Keeping the right humidity inside is key for comfort and health. Too much humidity can lead to mold and mildew, causing breathing problems like allergies and asthma. On the other hand, too little humidity can make your skin dry and cause static electricity. The ideal humidity level is usually between 40 and 50 percent for the best air quality.
Dangers of High Humidity
High humidity can really affect the air we breathe. It makes dust mites, mold, and mildew grow more. These can make asthma and allergies worse, leading to breathing problems and other health issues. Also, high humidity can make household items release more harmful gases, making the air worse.
Dehumidifier Use
- A dehumidifier can keep humidity at the right level, between 40-50 percent.
- Dehumidifiers pull out extra moisture from the air, stopping mold, mildew, and dust mites.
- When picking a dehumidifier, think about the room size, the humidity you want, and how efficient it is.
- Keeping the filters clean and emptying the tank is key for the dehumidifier to work well.
Keeping humidity in check helps make your home healthier and more comfy. It stops mold and other irritants from growing. Getting a good dehumidifier is an easy way to manage humidity and better your air quality.
Incorporate Indoor Plants
Keeping the air in your home clean is key to a healthy living space. Adding indoor plants is a simple way to do this. These plants act like natural air filters, removing harmful particles and boosting air quality.
Studies show that some houseplants are great at cleaning the air. For instance, the dracaena and bromeliad can take in harmful chemicals like acetone. NASA’s 1989 study even found that plants can change pollutants into oxygen, acting as a air purifier indoors.
To clean the air in a 1,500-square-foot home well, you might need about 680 indoor plants. But even a few easy-to-care-for plants, like ferns or lilies, can make a big difference. They improve air quality and make your home feel better.
Indoor plants do more than just clean the air. They also make people feel better. Being around plants can help you work better, learn more, and feel less stressed and sad. Adding these plants to your home makes it healthier and more welcoming.
When picking indoor plants for your home, think about how well they clean the air, how easy they are to care for, and if they fit with your home’s lighting and climate. With the right indoor plants, you can have cleaner air and a more lively, refreshing home.
“Indoor plants can turn pollutants into oxygen, making them a natural air purifier for indoor spaces.”
Test for Radon and Mitigate if Necessary
Keeping your indoor air clean is key to protecting your family’s health. Radon, a gas that comes from the earth, can get into homes and build up to harmful levels. High radon levels raise the risk of lung cancer. So, it’s vital to test for and fix radon if needed.
Radon Testing Methods
There are short-term and long-term tests for radon. Short-term tests last 2-90 days and show current levels. Long-term tests go for 90 days or more, giving a better look at average exposure. Choose the right test based on your needs and advice from radon experts.
Radon Mitigation Systems
If your home has high radon levels, you’ll need a radon system. These systems remove radon from under your home and send it outside. Experts can create a system just for your home to lower radon levels.
Dealing with radon is key to keeping your air clean and lowering lung cancer risk. Testing and fixing radon helps protect your family and makes your home safer.

Upgrade Fuel-Burning Appliances
Many homes in the United States use fuel-burning appliances like gas stoves, furnaces, and water heaters. These appliances are handy but can release harmful emissions. Upgrading to more efficient and eco-friendly options is key for better health and safety at home.
Proper Ventilation for Combustion Appliances
If switching to all-electric appliances isn’t possible, make sure your combustion appliances have good ventilation. Bad vents or chimneys can lead to dangerous buildup of pollutants like carbon monoxide. Regular checks and maintenance of these appliances, plus carbon monoxide detectors, can help avoid these risks.
- About 25 people die each year in California due to accidental CO poisoning from indoor combustion appliances.
- Vented combustion appliances can quickly build up pollutants indoors if not properly installed or maintained.
- Leaks or blockages in flues, chimneys, or vents can let pollutants into your home.
- Old appliances, wall or floor gas furnaces, propane appliances, fireplaces, and wood stoves are more likely to have issues.
Switching to all-electric appliances or ensuring good ventilation for your current ones can greatly improve your home’s air quality. This protects your family’s health. Always keep your appliances in good shape to stop harmful pollutants from building up.
“Combustion appliances need balanced air flow for efficient combustion and safe exhaust of pollutants to the outdoors.”
Replace Carpets with Hard Flooring
Keeping the air inside your home clean is key to a healthy life. Swapping out carpets for hard flooring is a big step in this effort. Carpets can catch dust, pet hair, and mold, which can make breathing tough and worsen asthma.
Allergens in Carpets
About one in 12 people in the U.S. have asthma, and the numbers keep going up. One in six asthma cases is linked to work. Carpets can be a big problem, hiding allergens that make asthma worse. Asthma hits around 7.1 million kids under 18 in the U.S., so it’s a big worry for families with young kids.
Cleaning Hard Floors
Hard floors like hardwood, tile, or laminate are easier to keep clean. Just sweep, mop, and vacuum them to cut down on dust and pet hair. Tile floors don’t have VOCs, resist moisture, and are easy to clean, helping to improve air quality. Hardwood floors last over 50 years with the right care and don’t have VOCs, making them great for cleaner air.
| Flooring Type | Allergen Resistance | Maintenance Ease | VOC Emissions |
|---|---|---|---|

To keep pests out, seal cracks around windows, doors, and walls. Sealing these spots well cuts down on outdoor allergens coming in. Also, use products that are low in VOCs or certified for indoor air quality during upkeep.
Mold Prevention
It’s important to keep your home dry to stop mold. Keep humidity between 40 and 50 percent to fight allergens, mold, and dust mites. Dehumidifiers are great for managing humidity and drying out your home. Clean vents in bathrooms and kitchens often to keep humidity in check.
Sealing up, managing moisture, and keeping pests away can make your home’s air cleaner. This means a healthier place for you and your family.
“Properly sealed and insulated building envelopes can prevent the infiltration of pollutants and control moisture levels, which is essential for maintaining indoor air quality.”
By doing these things, you can shield your home from the bad effects of too much moisture, mold, and pests. This ensures a clean, healthy living space.
Integrate Smart Surfaces
Using smart surfaces in your home and property can greatly improve indoor air quality, energy use, and the environment. These are materials and technologies that fight the urban heat island effect, manage stormwater, and boost community strength.
Cool Roofing Options
Choosing a light-colored or reflective roof is a simple way to use smart surfaces. Cool roofs reflect over 50% of the sun’s rays, unlike dark roofs which reflect only 15-20%. This means less heat in your home, lower cooling costs, and smaller energy bills.
Green roofs, covered in plants, also help by insulating and soaking up rainwater to stop flooding.
Porous Pavement Benefits
Porous pavement lets rainwater go through the surface and into the ground, cutting down on stormwater runoff and flooding risks. Porous pavement also helps recharge groundwater and lessen the urban heat island effect by reducing dark, heat-absorbing surfaces. Adding trees and greenspaces around your home boosts these effects even more.
By using smart surfaces, homeowners can cut down on indoor pollutants, save on energy bills, and help make their communities more sustainable. These solutions tackle climate change, urban heat, and water issues, making places healthier and more livable.
“Smart Surfaces can help cool cities by up to 5°F and reduce flooding.”
Smart surfaces are becoming more popular as cities and communities see their many benefits. By choosing wisely for roofing, paving, and landscaping, homeowners can help shape a sustainable future.
Improve Fresh Air Ventilation
It’s key to keep the air inside your home fresh. By opening operable skylights and vertical windows, you create a “chimney effect”. This lets out old, polluted air and brings in fresh air from outside. Using automated skylight controls helps keep the air moving, making your home healthier and more comfy.
Outdoor air is cleaner than indoor air, with fewer pollutants. Ventilation is important for a healthy home. But it’s not enough on its own to fight indoor pollution. Combining ventilation with other methods can tackle moisture, smells, gases, dust, and other indoor pollutants.
Using operable skylights and windows helps improve air flow. This reduces the risks of diseases, mold, and damage to your home. Experts say homes need at least 0.35 air changes per hour to keep the air clean.
