Buy 4 Robitussin Humidifier Replacement Wick Filter; Part # AC-813

Customer Ratings:

These filters have only one issue to keep it from being perfect they are a bit too short and narrow. It's a real pain to have to keep trying filters until you find one that can be relied on to be long lasting and has great performance. Now that I've tried this one several times I can honestly say it's the best one so far. Will certainly buy from Crucial Air again.

The product met my expectations. The filters work perfect in may Robitussin Humidifier as espected. The only problem, they came in an open bag, it was not really the most apealing package
