The pre-filters in your HEPA unit catch the larger particles in the air, what’s referred to as “hardballs and softballs.” They do the heavy work. Generally the pre-filters should be changed every three to six months. It is important to consider your environment in determining the frequency.
If your cleanroom sits in the middle of a warehouse or manufacturing area, your changing cycle is closer to three months, or maybe even more frequently. If your cleanroom sits in a pharmacy area, the environment will be cleaner. You can increase your change cycle to as long as six months.
Yes, you can use filters purchased from one of these outlets. We suggest you consult with a sales representative at the retailer and rely on a brand name filter. This may cost you a little more, but it is worth the investment. It is also important to make sure you get the right size and fit of pre-filter for your HEPA.
Again, it depends on your environment, but we suggest every five to seven years.

Yes. In rooms with walls of polycarbonate, use a jigsaw with a plastic blade. In vinyl, use a utility knife to cut an X where you want the hole. Punch holes in the vinyl at the end of the cuts to prevent them from tearing any farther. Use clear cleanroom grade caulking to seal the holes.
Simplex cleanrooms will accommodate coving. For best results, let us know in advance. This allows us to make alterations to the wall frame for optimal efficiency in your coving.
Simplex’s standard HEPA filters allow for changing the media from the outside of the room. Some cleanroom managers prefer HEPAs esignedd for changing the media from the inside. Simplex can offer HEPAs with this feature. Be sure to ask your Simplex representative if this is your preference.
If you turn of your HEPA filters, then you cannot use the cleanroom until you have done a complete clean, and depending on the level of clean required in your room, this might entail bringing in an outside service. If your cleanroom is going to be unoccupied, at night or on weekends, then leave the filters on at their low setting.
You need to have your cleanroom certified to the level required by the type of manufacturing or procedures that are performed in it. If the product you are manufacturing is regulated by a government agency, or you are contracting with a private firm that requires a certain level of clean manufacturing, they should have the cleanroom standards already documented.
Cleanroom certification is done through a contractor who is licensed to certify cleanrooms. These tests might include airborne particle counts, airflow velocity, airflow volumes and other procedures.
