My Buying Guides on ‘Lennox X6672 16X25X5 Furnace Filter’
When I was searching for the perfect replacement filter for my furnace, the Lennox X6672 16X25X5 caught my eye. Here’s what I learned from my experience and what helped me decide that this filter was the right choice for my home.
Understanding the Size and Compatibility
The first thing I checked was the size. The Lennox X6672 comes in a 16x25x5 dimension, which is slightly thicker than standard 1-inch filters. This thickness means it fits certain Lennox furnace models specifically designed for 5-inch filters. I made sure to measure my existing filter slot and consult my furnace manual to confirm compatibility. If you have a Lennox furnace or a similar model that supports a 5-inch filter, this filter will fit perfectly.
Filtration Efficiency and Air Quality
I was concerned about indoor air quality, especially with allergies in the family. The Lennox X6672 offers MERV 11 filtration, which strikes a good balance between capturing common airborne particles like dust, pollen, and pet dander without overly restricting airflow. For me, this meant cleaner air inside my home without putting extra strain on the furnace system. If you need higher filtration, you might look at other options, but MERV 11 worked well for my needs.
Durability and Material Quality
One thing I appreciated about this filter was its sturdy construction. The pleated design with a robust frame ensured that it didn’t collapse or bend during installation or use. This durability means it lasts through the typical recommended replacement period, which for me was about 3 months. I found that the quality materials helped maintain consistent airflow and filtration over time.
Installation Ease
Installing the Lennox X6672 was straightforward. The filter slides easily into my furnace’s filter slot without any hassle. I liked that the filter had a clear airflow direction arrow printed on it, which helped me avoid mistakes during installation. If you’re replacing your filter yourself, this ease of use is definitely a plus.
Price and Value
When I compared prices, the Lennox X6672 was reasonably priced for a 5-inch, MERV 11 filter. While not the cheapest option on the market, I felt the quality and performance justified the cost. For me, investing a bit more upfront meant better air quality and less frequent replacements, saving money in the long run.
Where to Buy
I found this filter available through several online retailers, as well as HVAC supply stores. Ordering online was convenient for me, and I made sure to buy from reputable sellers to avoid counterfeit products. Checking for warranty or return policies also gave me peace of mind.
Final Thoughts
Overall, the Lennox X6672 16X25X5 furnace filter matched my needs for size, filtration efficiency, and durability. If you have a compatible furnace and want a reliable filter that improves air quality without compromising airflow, this filter is worth considering. Just remember to check your furnace specifications and replace the filter regularly to keep your system running smoothly.
