Are these compatible to germ guardian ac4900

On the box it says compatible with germ guardian models shown in video. Hope this helps.

what are the dimensions of the filters?

The flt4825 hepa filter b replacement dimensions are 4.7in x 1.26in x 15.8in

are these filters compatable with Envion 4 Season: with air purifier,humidifier, heat and cool?

I use mine for my air purifier. You have to make sure you use exactly what the manufacturer recommends

Wil these fit the Allen T500?

These were replacement filters for a Germ Guardian air purifier. Type in your search for your specific brand and see what comes up. I have not heard of a Allen T500 before. Most filters will tell you in the description what type of filter it can replace.
