Customer Question

Can I use the Honeywell 1700 series air filter without a pre-filter for one day? I bought a used unit and replacement hepa filters, but no one mentioned I'd need to buy a prefilter also. Id like to use the unit tonight and look for the pre-filter tomorrow.

You are not going to hurt anything but you will want to make sure the hepa filter is clean before putting the new pre filter on when you get it.
