Michigan Filter First Law Compliance Guide

Michigan’s Filter First Law: What Schools and Child-Care Centers Need to Know

Updated September 2026

Michigan’s Filter First program has moved from implementation deadlines to ongoing compliance.
Schools and licensed child-care centers covered by the law should now be focused on maintaining filtered drinking water, replacing filter cartridges, completing required sampling, keeping accurate records, and correcting any remaining compliance gaps.

If your facility still has unfinished Filter First work, now is the time to review your Drinking Water Management Plan, confirm every consumptive fixture is properly addressed, and make sure required maintenance and testing are current.

If you are determining which replacement filter your school or child-care facility needs, our water fountain filter guide explains how to identify the correct filter by brand, model, and application. It also covers replacement timing, common filter types, and what to check before ordering.

What Is the Michigan Filter First Law?

Michigan’s Filter First laws took effect October 24, 2023. They include the Clean Drinking Water Access Act for K-12 schools and amendments affecting licensed child-care centers.

The laws are intended to reduce children’s exposure to lead in drinking water by requiring covered schools and child-care centers to manage drinking water through filtration, maintenance, sampling, and recordkeeping.

Covered facilities must:

• Maintain a Drinking Water Management Plan (DWMP)
• Identify fixtures used for drinking and food preparation
• Provide qualifying lead-reducing filtration at consumptive fixtures
• Maintain filters and replace cartridges on schedule
• Sample filtered fixtures for lead at required intervals
• Keep required maintenance and testing records
• Take corrective action when lead is detected

Michigan’s Filter First requirements apply to public and nonpublic K-12 schools and licensed child-care centers covered by the legislation. Family group child cares and private residence child cares are not subject to the same Filter First requirements.

Why Filter First Matters

Lead can enter drinking water through plumbing materials, fixtures, solder, and other components within a building. Schools and child-care facilities can also experience long periods of water stagnation, especially overnight, on weekends, and during school breaks.

Michigan’s approach focuses on reducing exposure at fixtures where water is actually consumed. Qualifying filtration must meet applicable requirements for NSF/ANSI Standard 53 for lead reduction and NSF/ANSI Standard 42 for particulate reduction.

Filter First Deadlines and Ongoing Requirements

As of September 2026, Michigan’s major initial Filter First implementation deadlines have passed:

• January 24, 2025: Schools and child-care centers were to complete their Drinking Water Management Plans.
• October 24, 2025: Licensed child-care centers were required to ensure that water furnished to children came from a filtered source.
• End of the 2025-2026 school year: Michigan schools were required to have approved filtration on consumptive fixtures as required by Filter First.
• Ongoing: Schools must sample filtered fixtures annually. Child-care centers generally sample filtered fixtures every two years.

What Counts as a Consumptive Fixture?

A consumptive fixture is a water outlet used for drinking or preparing food or beverages.

Depending on the facility, examples can include:

• Bottle filling stations
• Drinking fountains and bubblers
• Kitchen faucets used for food preparation
• Classroom faucets designated for drinking
• Faucets used to prepare beverages or infant formula
• Other outlets specifically designated for human consumption

Fixtures that are not used for drinking or food preparation can be designated non-consumptive. Required signage should be used so students, staff, and visitors understand that the water is not intended for consumption.

Correctly identifying consumptive fixtures is important because every unnecessary consumptive designation can create another fixture that must be filtered, maintained, sampled, and documented.

What Type of Filters Are Required?

Michigan Filter First requires filtration at the point where water is consumed rather than relying only on treatment where water enters the building.

Filters used for Filter First consumptive fixtures must meet applicable requirements that include:

• NSF/ANSI Standard 53: Lead reduction
• NSF/ANSI Standard 42: Particulate reduction

Common approaches include filtered bottle filling stations, qualifying faucet filters, retrofit applications, and approved filtration configurations for specific locations.

Are In-Line Filters Allowed?

In certain applications, yes. Michigan EGLE has issued guidance for in-line filtration in commercial kitchens, classrooms, and other necessary locations where a filtered bottle filling station cannot be installed.

An in-line installation is not automatically compliant simply because a certified filter is present. The filtration configuration, downstream plumbing components, maintenance plan, and other requirements must follow current Michigan guidance.

Ongoing Water Testing

Installing filtration does not eliminate Michigan’s testing requirements.

• Schools: Filtered fixtures must be sampled annually.
• Child-care centers: Filtered fixtures generally must be sampled every two years.

Michigan does not establish one statewide calendar date when every facility must sample. Sampling begins after filters are installed and continues according to the required frequency.

That makes accurate fixture records and sampling schedules especially important. A school or child-care administrator should be able to determine when each filtered fixture was last sampled and when it is due again.

What Happens if Lead Is Detected?

Michigan requires follow-up when sampling detects lead in water from a filtered fixture.

Results from 1 to 5 parts per billion (ppb): The filter status and installation should be checked, the cartridge replaced if necessary, and the fixture resampled according to Michigan guidance.

Results greater than 5 ppb: The fixture must immediately be shut off or otherwise made inoperable for consumption. Required signage must be posted, the filter cartridge replaced, and the filtered water resampled.

Facilities should retain sampling results and corrective-action documentation with their Filter First records.

Recordkeeping and Maintenance

Post-deadline compliance increasingly depends on maintenance and documentation, not simply whether filtration equipment was purchased.

A facility should be able to document information such as:

• Fixture identification and location
• Consumptive or non-consumptive designation
• Filter manufacturer and model
• Replacement cartridge model
• Filter installation date
• Cartridge replacement dates
• Filter status or error-code checks
• Sampling dates and laboratory results
• Resampling results
• Corrective and remediation actions
• Required signage and notifications

For administrators taking over Filter First responsibilities from another employee or contractor, reviewing the current DWMP and comparing it against the equipment actually installed in the building is a good starting point.

Filter First Funding Update

Michigan’s Filter First - Healthy Hydration program provided federal funding to help eligible schools and licensed child-care centers purchase and install qualifying equipment and cover certain related expenses.

The Healthy Hydration grant application is now closed. The program’s eligible expenditure period for reimbursement covered costs incurred through June 30, 2026.

Facilities that already received an award should continue to follow the state’s current reimbursement and grant instructions for that award.

Facilities that did not receive funding should not assume the original Healthy Hydration application is still open. Check current Michigan Filter First information for any future appropriations, reallocated funds, or new assistance programs.

Frequently Asked Questions

Who must comply with Michigan Filter First?
Michigan Filter First covers public and nonpublic K-12 schools and licensed child-care centers covered by the legislation. Family group child cares and private residence child cares are not subject to the same Filter First requirements.

Are the main Filter First deadlines still ahead?
No. As of September 2026, the main initial implementation deadlines have passed. Facilities should now focus on maintaining compliance and correcting any unfinished requirements.

Are point-of-entry filters enough?
No. Building-wide point-of-entry filtration by itself does not satisfy Michigan’s Filter First requirements for consumptive fixtures.

Can an in-line filter be used?
In certain applications, yes. Michigan EGLE provides specific guidance for in-line filtration in commercial kitchens, classrooms, and other locations where a filtered bottle filling station cannot be installed. The installation must meet the applicable Filter First requirements.

Do we still need to test water if we use filters?
Yes. Schools must sample filtered fixtures annually. Child-care centers generally sample filtered fixtures every two years.

What happens if a filtered fixture tests above 5 ppb for lead?
The fixture must immediately be shut off or otherwise made inoperable for consumption, required signage must be posted, the filter cartridge must be replaced, and the fixture must be resampled according to Michigan guidance.

Can we use existing fountains with new filters?
Sometimes. Whether an existing fixture can remain in service depends on the fixture, how it is used, the available filtration configuration, and whether the completed installation meets current Filter First requirements.

Is the Healthy Hydration grant still open?
No. The application is closed, and the eligible expenditure period covered costs through June 30, 2026. Existing awardees should follow the state’s current reimbursement instructions for their awards.

Staying Compliant After the Deadlines

Michigan Filter First is no longer primarily about preparing for an installation deadline. It is now an ongoing drinking-water management responsibility.

For facilities that completed their upgrades, the focus shifts to filter maintenance, cartridge replacement, sampling, recordkeeping, and corrective action when needed.

For schools or licensed child-care centers that still have unfinished work, review the DWMP, identify remaining gaps, and address those issues using current Michigan requirements and guidance.
