A little upset about air filters

Initially, I assumed that a higher MERV rating was better

I’ve been looking into how often I should replace the air filters in my gas furnace and a/c. I’ve also read up on the weird types of filters, hoping to invest in the best choice for superior energy efficiency and indoor air quality. While I’ve received a lot of comprehension, I’ve also gotten worried with the lack of definite answers. There are websites and blogs that command changing filters every week, while others say every more than five weeks is fine. I guess that if I have pets in the house, filters should be replaced more often. I have a miniature poodle, even though she doesn’t shed very much. I’m not sure if she qualifies as a reason to switch out filters more frequently. I used to guess that the air filter in the gas furnace and a/c was designed to improve the cleanliness and health of the living space. I was wrong. The filter protects the inner laborings of theh heating and cooling device from contamination. It traps dust, dander, pollen and other particles that would otherwise get inside and buildup on components. This accumulation gradually restricts airflow and makes it more difficult for moving parts to do their job. The system then needs to run more often and longer. It struggles to meet the thermostat setting and experiences greater wear and tear… Efficiency suffers and there’s an increased risk of malfunction, and plus, the system can distribute these pollutants into the breathing air which causes a health risk. This made myself and others guess that I wanted to buy the very best filters on the market. Filters have MERV ratings. The higher the rating, the smaller the holes and the more debris gets trapped. Initially, I assumed that a higher MERV rating was better. However, the smaller holes means that the filter becomes clogged more abruptly and requires replacement more often.
