Start with what others have suggested. Seal the best you can and replace your carbon. Carbon only last a couple grows or much less if the room has high humidity. Buy some peletized bituminum based carbon not granular or coco based carbons. If your scrubber is filtering room air this will help. If your scrubbing air as it is exhausted outside this will do nothing to help house odor. If nothing else get some strawberry air fresheners.
I've used almost everything except the ozone lights. Truth is scrubber works the best and everything else just helps a little. I use a negative ion generator, ozone generator, ona bucket, pinesol bucket and ona block in ducts.
