Know which filters need attention before walking every room.

Filter Status & Replacement Planning

For districts with Alen units across multiple classrooms, offices, nurse areas, and shared spaces, filter replacement can become difficult to track manually. The Alen app can help teams check filter status where supported, identify units that may need attention, and plan replacements more efficiently.

Filter visibility is available on supported connected units.

What the App Can Help You See

Units showing filter replacement needed

Units with low remaining filter life

Rooms with high usage or longer runtime

Priority spaces that should be checked first

Units that may have not been reset after a filter change

Buildings where multiple units need service

How to Check Filter Status in the App

Start with your device list.

Once supported Alen units are connected to the app, facilities teams can review individual unit details from the app dashboard.

1. Open the Alen app

  • Start from the main dashboard or device list.

  • Choose the purifier you want to review by campus, room, or device name.

  • Check the unit detail screen for filter status, filter life, or replacement indicators where supported.

2. Identify units that need attention
Note which rooms or buildings may need filter replacement or follow-up.

3. Plan replacements by location
Group replacement work by campus, building, room type, or maintenance window.

What to Look For

Use filter visibility to prioritize maintenance.

Filter status can help facilities teams move from reactive checks to more organized planning.

Look for:

  • Units showing filter replacement needed

  • Units with low remaining filter life

  • Rooms with higher usage or longer runtime

  • Priority spaces that should be checked first

  • Units that may not have been reset after a filter change

  • Buildings where multiple units may need service at the same time

Turn Filter Status Into a Replacement Plan

Move from one-off replacements to planned filter management.

For large districts, filter replacement should not depend only on walking room to room or waiting for individual users to report an issue. App visibility, installed unit counts, and filter status can help Facilities and Purchasing plan ahead.

A simple planning process:

  1. Review filter status across connected units

  2. Identify which units need replacement soon

  3. Group units by campus or building

  4. Estimate how many filters are needed

  5. Coordinate replacement timing with school breaks or maintenance windows

  6. Share estimated filter needs with Purchasing

  7. Request a consolidated quote or reorder plan

This can help districts:

  • Reduce manual filter checks

  • Avoid replacing filters too early

  • Reduce the risk of delayed replacement

  • Better plan filter inventory

  • Support annual replacement-filter budgeting

  • Coordinate Facilities and Purchasing around one plan

Why This Matters for Facilities Teams

Move from filter checks to planned replacement.

Centralized filter visibility can help facilities leaders move from reactive management to more organized district-level oversight.

Filter visibility can help facilities teams:

  • Reduce unnecessary room-by-room filter checks

  • Replace filters at the right time

  • Group upcoming replacements by campus or building

  • Better forecast replacement-filter needs

  • Coordinate Facilities and Purchasing

  • Plan replacement work around breaks or maintenance windows

Looking at filtration across the whole building?

Portable HEPA is one part of a broader indoor air quality strategy. If your facilities team is also reviewing HVAC filtration, Alen can help evaluate filter needs, replacement planning, and opportunities across the school

When to ask Alen for help...

Not sure how many filters your district needs?

Alen can help your team review your current Alen purifier setup, estimate replacement-filter needs, and identify opportunities to make filter planning easier across campuses.

This can be especially helpful if your district:

  • Has a large installed base of Alen units

  • Recently placed a replacement-filter order

  • Is unsure which units need filters

  • Manually checks filter lights room by room

  • Wants to plan replacement filters by campus or building

  • Needs help forecasting annual replacement-filter needs

  • Wants to coordinate filter replacement with school breaks or maintenance schedules
