Ordering Notes

• If you are replacing a WSO 20 first-stage panel and your existing filter matches 24" x 24" x 1.88", this is the correct format.
• WSO systems can use different stages and part numbers (first stage vs primary vs final). If you are unsure, send a photo of the label or the filter and we’ll confirm.
