Is this the same thing?** A: I order the Aprilaire kit for the model 600. It includes everything you would need to maintain the 600. I had not done anything to mine in about 10 years except change the filter. It took me about a half hour to do everything. If you clean up some of the original parts you can use them for a spare. I think it's a nice kit. **Q: What are all the parts included in this maintenance kit 4838?please itemize** A: Hello. Thank you for the message. This listing is for all the items shown in the photo. A filter, humidifier orifice, in line strainer, scale control insert, water distribution tray, feed tube, and drain spud. Please let us know if you have any additional questions. Thank you! **Q: The water supply strainer that came with my kit (black plastic) is too long to fit into the solenoid water valve inlet. Wrong Part or what?** A: It fit into my factory water valve inlet port taper part in first, make sure that pieces of the old strainer are not stuck in your valve. **Q: The unit that I am replacing has 2 round cups at the bottom of the filter holder. Buy replacement maint kit doesn’t include this part. Will it work?** A: The maintenance kit you are buying does not have round cups on the bottom. If you are using this maintenance kit in another type of unit..I don't know. I have the model 600 and there are no round cups on the bottom. If the water can drain through the bottom then it should work ## Frequently Bought Together - AprilAire 4839 Humidifier Maintenance Kit with Water Panel Model No. 35 Humidifier Replacement Filter for AprilAire Whole-House Humidifier Models: 600, 600A, 600M - AprilAire H635EZ1A Humidifier Filter/Water Panel Assembly Replacement Kit for AprilAire Whole-House Humidifier Models: 600, 600A, and 600M - AprilAire 4040 Solenoid Valve, 24 Volt for AprilAire Whole House Humidifier Models 400, 400M, 500, 500M, 600, 600M, 558, 550A, 550, 568, 560A, 560, 700, 700M, 768, 760A, 760, 0.5 ounces --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ro/products/18221923-4839-maintenance-kit-with-water-panel-model-no-35-replacement](https://www.desertcart.ro/products/18221923-4839-maintenance-kit-with-water-panel-model-no-35-replacement) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-05-11*
