We have an older nonstandard plenum...Filtrete filter can easily be custom cut to desired size

This is the best working filter we have used. Will buy again.

I takes out the particles and I feel my house is cleaner and so are my lungs.

Would recommend purchasing online, better pricing. Works well.

My son has asthma, so I'm happy of how well it does filter the air.

Ive always used filtreye filters in my home and always have been satisfied with them.

[Employee of 3m-filtrete] I can always count on excellent performance from my Filtrete filter.

Catches alot of dirt, dust and hair. I have to change it every 2 months, but worth the $.

These are very good quality filters. I have been using these filters for years.

I've been using these filters for years....They pull a ton of crud out of the air! : )
