This is the place to go if you ever have a crazy size air filter that you need. They custom make any size for you and they are very, very reasonable price

Terrible company to work for. A negative review was posted and they wrote 2 fake ones After to make them look better. They had no reviews for a year but then had two positive ones back 2 back after a worker left a bad review. The front desk lady is always changing. The bosses are so bad and no one is happy. The bosses are stuck up and dont look out for there workers and only care about them.

I know they will write another fake good review just like they did on glassdoor&indeed the pres. of company said every one is replaceable. how is this a good place if they said that DO NOT WORK FOR THEM
