Review: Works, but cost is 6 times what it should be - Cost is way too high, but what do you do. I think you could buy the stuff in bulk and cut it yourself....should be about $5
Review: Nice product, seems to be a little high price for what you get, but works well. - I was vacuuming the existing fiberglass panel on my furnace air filter, and accidentally sucked it into my shop vac. It was super dirty already, and a little bit worse for wear, and so getting it sucked into my shop vac was the nail in its coffin. I decided it wasn't worth trying to fish it out and clean it off. This replacement set installed very quickly and easily. I used 3M spray glue, by spraying that on the plastic panel, and then sticking this replacement fiberglass panel onto that once the glue was tacky. Worked really well. I used masking tape and some cardboard to protect other areas when I was spraying the glue on before afixing the fiberglass. The one star removal is because it seems like this product should cost about $10 or more or less for what you're getting. Just seems priced unreasonably high, for what you're getting. Having said that, this does work well, without a need to try to make something else work and guess if it will perform well in your furnace air filter. So, even though the price is more than what I wanted to pay and more than I thought it should be, I would still buy this again, rather than trying to cobble something together (with some other type of foam or fiberglass pad).

### ⭐⭐⭐⭐⭐ Easy to Install
*by D***T on June 27, 2021*

I replaced my furnace and A/C unit last July, but kept my old Aprilaire filtering unit since it was still working well and would've been a waste of money to purchase a new one. However, as I was replacing the old filter from one year ago I noticed the fiberglass panels on the inside of the filter case were black as soot, and wondered if there were replacements available for purchase. A quick Google search pointed me to Amazon and sellers that had these replacement parts. They arrived quickly, and I installed them with ease. The best thing was that I was able to completely vacuum out the entire case and surrounding area inside metal duct attached to the Aprilaire unit. Glad I did as I saw several "clumps" of objects and dirt that may have affected the performance of the filter unit. Now that it's all fresh and new I'm good for quite a few years but will replace them when needed. As always, the filter gets replaced once a year.
