How to Pilot SecureAire Filters

A Step-by-Step Guide for Facilities Teams

Cut HVAC energy use, extend filter life, and improve indoor air quality—without disrupting operations.

Piloting R-Zero’s SecureAire filters is a smart move for facilities teams seeking to enhance HVAC performance and air quality while achieving energy savings.

This guide walks you through how to plan and execute a data-driven pilot.

Step 1: Identify a pilot location

Select two air handling units that are similar in the following ways:

• Size in air volume (CFM)
• Location served and activity pattern within that location
• Duty cycle (i.e., hours of operation and working at similar CFMs)
• Energy monitoring is available

One AHU will be your “Control” unit and provide a baseline. Ensure it is functioning properly with existing MERV-13 or higher filters without filter bypass or power disruption. Note the date of the last filter replacement and of any replacements during the pilot. The other AHU will be your “Pilot” unit, and will have its filters replaced with the R-Zero SecureAire filters and demonstrate pilot performance.

Step 2: Pre-Installation Baseline & Sensor Check

Before installing SecureAire filters, ensure you’re set up to measure differential pressure (DP) effectively in the Control and Pilot AHUs. Use one of the following methods, listed from most to least preferred:

Option	Scenario	Recommended Approach
1️⃣	BMS with Existing DP Sensor	Facilities manager provides monthly DP readings or trending data from BMS to R-Zero.
2️⃣	BMS Available but No DP Sensor	Install DP sensor (e.g., Setra 267) and connect to AHU/RTU controller. Facilities manager provides monthly DP readings or trends
3️⃣	No BMS Available	Deploy wireless DP sensor with cloud monitoring (e.g., Efento Cloud). R-Zero accesses DP data directly, minimizing facility staff involvement.
4️⃣	No Sensor Deployment Feasible	Use manual DP logger or calibrated Magnahelic gauge for periodic readings. Suggested tools: FLUKE 922 handheld manometer or DWYER 2008 analog gauge.

Step 3: Install SecureAire Filters

Once your baseline is complete and sensors are verified:

• Install SecureAire filters into the designated Pilot Unit.
• Ensure tight fit with no filter bypass—use R-Zero’s simple installation guide.
• Document the installation date for tracking performance over time.
• Monitor the Initial Pressure Drop after Installation

Note: SecureAire filters are designed to fit existing filter tracks—no retrofits or construction required.

Step 4: Monitor Performance 

Track these key metrics for both the Pilot and Control Units:

1. Differential Pressure (DP):
   • Monitor DP following the process and options above in Step 2.
   • This helps assess airflow resistance and energy draw over time.
2. Energy Consumption:
   • Use submeters or BMS-integrated sensors to track fan energy usage continuously.
3. Maintenance Schedule:
   • Note your typical filter replacement cycle and dates in the Control unit.
   • Compare longevity by comparing pressure drop between pilot and control units at the end of the pilot; SecureAire filters typically last 2–3 times longer than standard filters.

Step 5: Evaluate Pilot Results

At the end of the pilot:

• Compare DP trends and energy use between the Pilot and Control Units.
• Project maintenance savings based on estimated replacement cycles (fewer filter changeouts = lower OPEX).
• Quantify air quality improvements if IAQ sensors are available.

R-Zero will work with your team to compile a results summary and ROI snapshot.

Step 6: Expand Strategically

With clear savings and performance data in hand, you’re ready to scale:

1. Expand within the pilot building (e.g., additional AHUs).
2. Roll out to other buildings, coordinated with facilities, finance, and leadership.
3. R-Zero supports stakeholder engagement—including materials and meeting prep for Superintendents, Boards, and sustainability teams.
