How to Find the Optimal Time to Replace Your Air Filter: Guide to Energy Efficiency and Cost Savings

Writer's picture: Amar MAmar M

Knowing when to replace your air filter can be a tricky affair, caught between energy efficiency and costs. To make your life easier, we've designed a calculator that estimates the threshold for when to order a new filter and when to schedule maintenance. All this is made possible by real-time data from the Ellenex PDT2 - Differential Pressure Sensor.


Optimal Time to Replace Your Air Filter: Guide to Energy Efficiency and Cost Savings

The Importance of Accurate Timing

Replacing an air filter too early or too late can cost you—either in the form of unnecessary replacements or in lost energy efficiency. Our calculator aims to find the sweet spot, helping you maximize performance and savings.


Factor 1: Energy Efficiency

A clogged filter causes your HVAC system to work harder, reducing its efficiency and increasing your energy bills.


Factor 2: Costs Involved

Both the price of the new filter and labor costs should be considered to accurately determine the most cost-effective time for a replacement.


Ellenex PDT2 - Differential Pressure Sensor

This sensor provides real-time monitoring of your air filter's differential pressure. The data it generates is crucial for determining the best time for a filter replacement.

  • Instant Alerts: Get notified the moment your readings hit the threshold.

  • Cost-Effective: Save money by replacing your filter only when necessary


How Our Calculator Works

Our IoT-based calculator uses data from the Ellenex PDT2 sensor to estimate the optimal differential pressure threshold for two key actions:

  1. Ordering a New Filter: It calculates the point where the loss in energy efficiency and the cost of a new filter balance out.

  2. Scheduling Maintenance: It calculates when the increasing labor costs and further efficiency loss make it optimal to replace the filter.


FAQs


1. Can I install the Ellenex PDT2 myself?

While the Ellenex PDT2 is designed for easy installation, it's always recommended to consult a professional for the initial setup.


2. Is the Ellenex PDT2 compatible with all HVAC systems?

The Ellenex PDT2 is compatible with most modern HVAC systems. However, for specific compatibility queries, it's best to contact Ellenex directly.


Gone are the days of guesswork and manual monitoring. With the Ellenex PDT2 - Differential Pressure Sensor and our specially designed threshold calculator, you'll know exactly when to order a new filter and schedule maintenance, keeping your system efficient and cost-effective.
