Product review (5 stars): "Trane", Humidifier Replacement Water Panel for Model: HUMD300A.
This Humidifier Pad Replacement Water Filter is the part: A35-PR, manufactured by the company: BestAir Pro, a U.S. company based in Hampshire, IL, USA. Is identical to the model that come with the humidifier manufactured by Trane brand, model: HUMD300A. This part, A35-PR, also can be used with other models from other brands like Aprilaire, Honeywell, etc ... Always before buying anything, you should first seek the exact model you have and check on that company's website or by calling the company and be certain of the part or model for your humidifier. It is also very important to always insert your new water filter pad with the Water Mark on Top. This Humidifier Pad Replacement Water Filter, part: A35-PR, is of exceptional quality. I highly recommend it to everyone.
