With the right air filter, you improve HVAC efficiency and air quality. When an air filter isn’t working properly, you’ll likely see the signs. Allergy and asthma symptoms may worsen. Or you could notice a surge in your energy bills. For normal usage, you’ll want to change air filters between one to three months, depending on the type of filter you purchase.
MERV Ratings
To help shop for Filtrete filters, you should first analyze your household’s air quality requirements. MERV ratings score filters from 1 to 16. Most households will likely want air filters with a minimum rating of 8. MERV 8 air filters will remove small particles from the air such as dust, dust mites, and lint. You will also notice a reduction in foul odors permeating the air. Households with family members that suffer from allergies or other health issues will want to look at the air filters with MERV ratings of 11 and 13.
Changing Tips for the 14×30 Filter
Ideally, you will want to set reminders to change your air filter every three months. To remind yourself, you should write the date of installation on the air filter before replacement. Then, write the replacement date on your calendar or set a reminder on your smartphone’s calendar. If you notice any signs of poor air quality, you can always change the air filter sooner.
Air filters take minutes to replace and can be done by simply sliding the new version into the designated compartment on your HVAC system.

Nitrogen Dioxide Emissions
Nitrogen dioxide is a pollutant formed as a result of burning fossil fuels. Emissions will come primarily from cars, trucks, buses, and power plants. People who live in high traffic areas are typically exposed to high levels of nitrogen dioxide. Certain groups of people such as the children, elderly, and those with respiratory disease are at risk for having adverse effects when carbon dioxide levels are high.
The short-term effects of nitrogen dioxide exposure are significant. Asthma symptoms may be aggravated and the person may start developing symptoms such as difficulty breathing, coughing, and wheezing. Over time, respiratory infections are more likely to occur due to the poor air quality.
Human health is not the only thing affected by nitrogen dioxide emissions. Our planet will suffer the adverse effects as well. Nitrogen dioxide can interact with other atmospheric chemicals and lead to the formation of acid rain. According to the United States Environmental Protection Agency, acid rain damages fragile ecosystems including lakes and forests. Haze is also made up of nitrogen dioxide particles and limits visibility in areas. Coastal waters also become polluted due to the nitrogen dioxide found within the air.
Tips for Reducing Nitrogen Dioxide Emissions:
- Carpool
- Take public transportation
- Reduce engine idling
- Tune up engines regularly
- Practice good energy conservation at home and at work
