Dave hasn’t been a big fan of the poor air quality in his cabin. This led to doing some research mixed with troubleshooting things around the cabin. Dave did manage to discover that his cooling system was at fault. He had been replacing cheap air filters that were inefficient when it came to air quality. This led to the central cooling system blowing out awful air quality making Dave’s cabin not very conducive. The HVAC worker who did the inspection advised Dave that he should opt for HEPA brand air filters for his cooling unit. HEPA brand air filters are amazing and work as indoor air cleaners improving air quality. While these aren’t the same as cabin whole-cabin air purifiers, the HEPA air filters are a close second. Learning this prompted Dave to opt for the high-priced HEPA air filters for his cooling system. From then on, Dave has been enjoying better air quality within his home. The difference is quite remarkable. Dave feels a lot better in terms of breathing. He’s stopped having nasal blockage issues before sleeping as well. The cooling system with the HEPA brand air filters really pumps nice air quality into his cabin now. Dave is always grateful the HVAC worker took time to show him the best air filter to use. .
