Tier 1 air filters are high-efficiency filters designed to capture a significant amount of airborne particles, including dust, pollen, and other allergens. They typically have a Minimum Efficiency Reporting Value (MERV) rating of 11 or higher, indicating their ability to trap smaller particles effectively. These filters are commonly used in residential and commercial HVAC systems to improve indoor air quality and reduce the load on heating and cooling equipment. Regular replacement is essential to maintain their effectiveness.

Older homes, especially ones with a history of smoking, new renovations, or fresh HVAC systems, can get hit with a mess of air quality issues. Odors, irritation, just that weird “something’s off” feeling. The good news is, it’s fixable, and plenty of people have managed to clear the air with the right moves. Here’s what’s worked for others: 1. Ventilation Changes Everything When a house is sealed up tight, it traps all kinds of stuff: VOCs, old smoke, chemical smells from renovations. Installing an ERV to bring in fresh air and kick out stale air almost always helps. Fresh air dilutes the bad stuff way faster than any air purifier. 2. Spray Foam + Low Ventilation = Trouble Once spray foam cures, it’s generally safe—but if the house doesn’t breathe, leftover smells and VOCs can stick around. Boosting ventilation usually clears up things like burning eyes or nose irritation within a few weeks. 3. Old Smoke Smell? Seal It Up If nicotine or tar are still in the walls or ceilings, sealing those surfaces with a shellac primer is one of the best long-term fixes. Lots of folks only learn about this after the smell won’t go away, but it still works—even years later. 4. Ductwork + New AC Doesn’t Spread Old Smoke New ductwork and a fresh AC system mean you’re not dragging around old smoke or stale air. Since the house never had old ducts, you’re starting with a clean slate. Better ventilation gives your home a real chance to get rid of lingering stuff, not just push it around. 5. Health Symptoms Often Decrease as Fresh Air Cycles In Most people notice a difference once fresh air starts cycling through. Headaches ease up, people feel less wiped out, and breathing just gets easier. When humidity levels settle and those weird chemicals (VOCs) clear out faster, life at home just feels lighter. 6. What You’re Doing Is Exactly the Right Direction Honestly, you’re on the right track. Using an ERV, adding a dehumidifier, tracking down the sources of odors, and boosting air exchange—that’s the kind of approach that’s helped a lot of folks in the same spot. Stick with it. Balance your new gear, give it some time, and you’ll see things get better. It feels like a lot right now, but this doesn’t last forever. Plenty of homes with way bigger problems came back to life. Yours will too.
