AHU Pre-Filter Washing and Replacement

Washed Where Possible, Replaced Where Needed — Not Defaulted to One or the Other

A pre-filter that's washed past its useful life restricts airflow just as much as one that's replaced unnecessarily when a wash would have done. EKG M & E Sdn Bhd provides AHU pre-filter washing and replacement for building owners and facility managers across Malaysia, deciding correctly between the two rather than defaulting to whichever is quicker.

What We Offer

🔍 Site Assessment & Filter Type Check
We assess the AHU pre-filter section on site, confirming filter type and whether it's washable or intended for replacement only.

📊 Existing Filter Condition Inspection
We inspect the pre-filter for loading, damage, or media degradation, establishing whether washing is genuinely still viable.

📏 Pressure Drop Measurement
We measure pressure drop across the pre-filter section before service, confirming the extent to which loading is restricting airflow.

🧹 Thorough Filter Washing
Where washing is appropriate, we clean the pre-filter thoroughly, removing embedded dust and buildup a quick rinse would leave behind.

💧 Drying Before Reinstallation
We ensure washed filters are fully dried before reinstallation, since residual moisture promotes microbial growth and reduces performance.

⚙️ Wash Cycle Limit Check
We check how many wash cycles the filter has already undergone, since repeated washing eventually degrades media beyond effective use.

📦 Correct-Spec Replacement Where Needed
Where washing is no longer appropriate, we replace the pre-filter with the correct specification part matched to the AHU's housing and airflow rate.

🛡️ Housing & Seal Check
We check the filter housing and seals during service, since a damaged seal lets unfiltered air bypass the pre-filter regardless of its condition.

🔄 Correct Reinstallation
We reinstall washed or new pre-filters correctly, seating them fully against seals and securing them with the correct retention mechanism.

🌀 Post-Service Airflow Verification
We verify airflow and pressure drop after service, confirming the pre-filter is performing within expected range.

📋 Service Report
You receive a clear report covering the decision made, work carried out, and airflow verification results.
