X6672 Lennox Healthy Climate 16x25x5 Merv 16 Filter

These are excellent filters and the only ones available in this size with this very high MERV 16 rating. I wanted the best filtration I could achieve after discovering the installer of my brand new Trane HVAC system had fitted a totally inadequate filter holder with a 1-inch gap allowing dust from some remodeling we were having done to pass around it and get into our house.LESSON: Check whether the filter in your HVAC system is a tight fit or you may as well not bother to fit a filter at all and certainly not an expensive one. So I fitted a Honeywell 16x25x5 EnviraCaire Elite fiter housing which is supplied with a MERV 13 filter which is the highest available from Honeywell. The filters supplied with this housing do not fit particularly well and air can flow around them unless additional gasket material is applied, so I was curious to see how well these Lennox MERV 16 filters would fit in my Honeywell filter housing. The fit was no worse than the Honeywell ones but the air gap around the filter would have rendered it almost useless without additional gasket material. Fortunately it is very simple to make an airtight fit using 3M 1/2-inch x 3/8-inch self adhesive foam window sealing strip available from Home Depot etc. I applied the strip to all four sides and carefully inserted the filter in the housing being vigilant not to tear the foam strip. The foam strip compressed very nicely against the interior walls of the filter housing and voila, a perfectly sealed filter installation. The filter is doing a fantastic job. I had the system serviced by a highly recommended installer who said that I should not use these filters in addition to the filters on all of our HVAC return grills as it would stress the furnace. HOWEVER, with new filters on the inlets of all our returns PLUS this MERV 16 filter, our furnace is working perfectly well AND the MERV 16 filter has collected dust that would certainly now be in my house. I am very satisfied. Obviously these filters should be changed regularly, especially in a dusty environment with pets etc.

A+++

BEST PRICE AVAILABLE

The unit was everything expected and at a lower cost than I could get it locally.

The filter came before the stated received date. It was the correct size and works great. Easy to order. The price was in line or a little cheaper than other sites.

shipped free &quickly. Fits the system perfectly

replacement for my furnace filter

Ive never used a Merv 16 but thought Id try this. It arrived in very good packaging, the filter looks well made but I wont actually use it until approx. 3 or 4 more months as thats when my present filter (Merv 11) will be due for a changeout. So I may give it a 5 star later once I update my review.

Perfect. Thanks

As ordered. Quick shipping. I will be getting another one next year and the year after that and etc. The company that comes out and handles maintenance on my unit charges $200 for one. This is much better deal
