MERV 11 does the trick during pollen season in Florida changing it every 3 weeks during Jan-March. Will try backing off to every 6 weeks when the worst is past. That appears to be the recommendation for highly allergic individuals, on a routine basis, throughout the year.
So, its difficult to be excited about air filters. But I would say that the experience with this company is always a good one. They are always professional and the product arrives quickly. So there you have it. Exciting stuff, huh ??
They do not cut the filters as advertised (shown video) for odd size. Cut in the middle and pieced together 2 pieces which created inaccuracies on length and width and STRAIGHTNESS! All varied. Dont believe what they advertise and you may read and see! Soooo typical but too bad but they are guilty of false advertising or customer deception - no matter how slick or sincere their owner appears.
