With the DROP Single Tank Aeration Filter, air is injected into the top of the tank converting ferrous iron to ferric iron after untreated water has passed through the control valve preventing the control valve from fouling with iron. This process helps to eliminate plugged seals and spacer, dried-up seals, jammed pistons, and other issues associated with iron build up.

Key Features:

  • Air injected into the top of the tank converts ferrous iron to ferric iron after untreated water has passed through the control valve, preventing it from fouling with iron
  • Effortlessly monitor and adjust cycle times using the DROP App
  • Stay informed with real-time notifications, texts, and emails for system alerts
  • Enjoy peace of mind with a comprehensive 5-year warranty included

There are 2 types of Aeration Filters to choose from:

Smart Blend Media – Best for iron as it increases the pH.

Sulfur Reduction Media – Best for sulfur and does not increase the pH.

DROP offers the only water filters in the world that protect your home from water leaks in addition to providing all the benefits of treated water. When paired with DROP Leak Detectors through the DROP Hub, this system provides all the benefits of a top of the line water filter, home leak protection, and a water conservation system in one.

  • Manganese: Often presents itself as brownish-black particles, staining laundry and fixtures, and giving water a bitter, metallic taste.
  • pH: The pH level of water indicates its acidity or basicity, and influences the solubility and toxicity of contaminates in water.
  • Sediment: Finely dispersed particles such as sand and rust.

The Single Tank Aeration Filter is easy to install and durable, handling large volumes of water with efficacy. Step up to a higher standard of water quality with the DROP Single Tank Aeration Filter.

The DROP App

  • The DROP app offers real-time alerts and notifications that keep you constantly updated about your water usage and system status.
  • Not tech-savvy? No problem! Everything you need, from controls to troubleshooting, is found within the app. Its intuitive design makes it accessible, easy to navigate and understand.
  • The app enables easy transition between different DROP systems, making it perfect for those managing multiple locations.

How It Works

  • Filtration Stage: Your home’s water enters through the inlet pipe, passing down over the media bed. The media traps and reduces the potential harmful contaminants that can disrupt your water quality.
  • Purified Water Distribution: The filtered water then circulates throughout your home via the outlet pipe, providing you with cleaner, safer water for drinking, cooking, bathing, and more.
  • Backwash Cycle: A backwash cycle occurs periodically to remove the contaminants that are trapped by the media, cleaning and reorienting the media for continued effective use.

Superior Quality and Protection at Your Fingertips.


Your water used to taste bad, metallic. But then you installed the DROP Single Tank Aeration Filter. And now? Pure, unadulterated deliciousness.


The specifics are a little technical. Actually, they’re a lot technical. But you don’t need to understand how oxygen injection works to turn ferrous iron to ferric iron to fully appreciate how clean your pipes and valves are post installation.


As part of the full DROP Smart Water System, this filter is a critical step in the process of ensuring clean, pure water and preventing leaks before they become a problem. Plus, you have full control through the DROP app from anywhere.

The Benefits of DROP

The DROP App contains a robust amount of notifications to keep you informed. Everything from Leak Detection to Low Salt notifications, DROP has your back for all system events and items. They can be configured to push notifications, text messages, and emails.

Below is a list of all of the unique notifications available to you.

Automatically Respond to Detected Leaks

Worried about water leaks and damage to your home? With DROP Leak Detectors, you will never have to worry about that again! These sensitive devices can detect small traces of water where there should be none. You can configure these leak detectors to notify you of the issue as well as automatically shut off your water through your softener, filter or home protection valve to prevent further leaks and damage.

Long Flow Notification

Has someone left a sink running? This notification will inform you if water is running longer than expected based on your preferences.

Valve Error Notification

Has your softener or filter control valve malfunctioned? This notification will provide you with the correct information to help assess any valve issues in your water softener and/or water filter control valve.

Component Communication Lost Notification

DROP constantly communicates with its device endpoints. If your system is having trouble communicating with one of the devices, you will be notified and able to fix the problem.

Low/High Temperature

DROP Leak Detectors have the ability to notify you of temperature changes based on your preferred temperature ranges. If you lose heat in your home, your DROP Leak Detector will notify you.

Low Salt Notification*

Is your water softener running low on salt? With our patented DROP Salt Sensor, you will be notified if more salt is needed to continue providing softened water.

Slow Leak Test**

This unique test provides the status of your water system overnight by checking for small water leaks. By depressurizing your water pipes while you sleep, we can detect even the smallest leak in your system and help you identify where that is.

Filter Cartridge Notifications

Is your Whole House Cartridge Filter in need of a cartridge replacement? This notification will inform you to replace your cartridge to continue filtering and cleaning your home water.

Power Loss/Restored Notifications

Ever lose power to your important electronic devices and not know about it? This notification will notify you of this event. Never fear, as DROP uses battery backups on nearly all of its devices to continue operating without power.

Low Battery Notifications

DROP Leak Detectors and other DROP components operate on batteries using very low power consumption capable of lasting for years. If these batteries run low in power, you will know when to replace them.

Leaky Toilet Notification

Our technology is able to detect whether your toilet is leaking or not by pinpointing how much water is used during and after a flush.

Water Usage Surpassed Setpoint

Want to know when you have used a certain amount of water? This notification will let you know when you have crossed water use thresholds based on your preferences.

* Specific notification for DROP Water Softeners only.
** Specific notification for the DROP Home Protection Valve only.
