I have a room air purifier. It's good to leave on in the bedroom all of the time. We use one in the house air system too.
The hard part is keeping up when to replace the filters and the cost.
There are some companies that sell the kind with washable filters that are based on ionized air.

When life throws you lemons....
Pick them up and throw them right back at them! :))
