Keep your EverFlo 5L oxygen concentrator running clean with the Nispira replacement intake filter. Installed at the air inlet, it helps reduce dust from entering the equipment during normal operation, supporting consistent airflow and stable performance over time.

Product Overview

This Nispira intake filter is engineered as a compatible replacement accessory for standard 5L oxygen concentrator systems, including Philips Respironics EverFlo style units. The filter combines a durable plastic outer housing with an internal filtration layer, helping it maintain shape and structural stability while airflow passes through. The compact, precisely sized design ensures a secure fit within compatible units, and the simple drop-in installation requires no tools.

Fit Verification

Because oxygen concentrator models vary in inlet size even within the same general "5L" category, please compare the inlet diameter and overall dimensions above against your unit's original filter before purchasing. This helps ensure a secure, proper fit.

Installation

1. Turn off and unplug the oxygen concentrator before beginning.
2. Locate the existing intake filter at the air inlet of the unit.
3. Remove the old or worn filter.
4. Align the new Nispira filter with the inlet opening and press into place — no tools required.
5. Power on the unit and confirm the filter is seated securely.

Filtration and Maintenance

Over time, intake filters accumulate dust and particulate matter, which can affect airflow performance. Routine replacement is recommended as part of regular equipment maintenance to help support consistent operation. Inspect the filter periodically and replace it if visibly dirty or if airflow seems reduced.

Compatibility Notice

This filter is designed to be compatible with Philips Respironics EverFlo 5L oxygen concentrators and similar standard 5L units using the same intake filter dimensions. Please verify the dimensions listed above against your device's original filter before purchasing, as oxygen concentrator inlet sizes can vary by model.
