Clean Vents and Replace Air Filters

You may have your cleaning routine perfected and notice that your house still feels dusty. This happens when you don’t replace your filters regularly. However, it also occurs when the filter is full of dust, dander, and other pollutants.

The air can not flow through the filter well, which starts to affect the HVAC and causes it to break down. Therefore, set reminders on your phone or a calendar. So you do not forget to change the filters. 

For individuals with allergies or asthma, it’s even more crucial to change the filters. This is because the irritants such as pollen and dust are still in the air.

You may notice you are sneezing or coughing more than usual it’s always best to check with a doctor. However, it could be dirty filters.

Some believe that filters are an extra expense. Nonetheless, they could be causing your energy bills to be more expensive than usual.

This is because your system has to work harder to reach the desired temperature. The good news is that you can change your system’s filters even without technical know-how.

Types of Filters

The type of filter makes a difference in how often you need to replace the filter.

If you opt for a fiberglass filter, they are easy to get your hands on. However, they are inefficient as they do not pick up smaller particles, meaning they need replacing every 30 days. 

Washable filters are a great way to be sustainable. Although, once you wash them, you must wait until they are fully dried before restoring them to the HVAC.

This means that your air conditioning is off for a few hours and is slightly inconvenient. 

Pleated filters are a good option as they trap the most particles due to their pleat structure. HEPA filter structure is on the more expensive side, but they trap 99.97% of particles. Hence, they are a good option for allergies and asthma.


The minimum efficiency reporting value (MERV) indicates how much pollutants are removable from the air. The MERV ranges from one to twenty, with twenty filtered more of the air.

A MERV of one to four is not the best option. They only pick up larger particles.

An eight MERV is the most popular as they pick up most pollutants. A MERV 11 is beneficial for those with animals as it picks up most dander, dust, etc.

Opting for a MERV of 13 or higher should only be used if necessary, as it can cause damage to the HVAC as it picks up even the smallest particles!
