Hi-Flo^® ES is the Only Filter of its Kind Designed to Work Without a Prefilter – a Huge Advantage for Users in Cost, Labor and Inventory.

There are several advantages to working without a prefilter, including energy savings, filter cost, plus labor, waste and transaction costs. It's important to know that without the prefilter Camfil Farr still provides a low energy, low waste, low carbon footprint final filter that is superior to all other options. The only exception may be some 4V box-style filters. The Hi-Flo ES performance is superior to all other 12", 22" and 3" pocket filters.

Considering all factors, eliminating the prefilter can save $75 to $100 per filter opening, per year. Energy savings comprises about 80% of this total savings, so you will find that the Hi-Flo ES is a phenomenal "free" or "break-even" investment after just one to three months.

The Hi-Flo ES is a high-efficiency ASHRAE grade pocket filter that combines lowest energy use and longest service life. Hi-Flo ES can last a year or more without a prefilter, while maintaining its high rated efficiency.

The Hi-Flo ES was engineered for efficiency and sustainability. Benefits include:

• Lowest energy costs – The Hi-Flo ES maintains a low pressure drop that saves 30% of HVAC-related energy cost when compared to other filters.
• Less freight – The Hi-Flo ES requires fewer filter changes, which means freight and inventory costs are lowered immediately – and permanently.
• Less labor – Fewer filter changes per year also lowers labor costs, and allows maintenance personnel to be assigned elsewhere.
• Less weight – Hi-Flo ES is so strong, it withstands up to 10" w.g., yet it's lightweight, with a unique snap-to-seal pocket retainer that prevents filter bypass.
• Less waste – Hi-Flo ES directly reduces landfill burdens, while lowering your carbon footprint. It is the greenest pocket filter on the market today!
• Simplified stocking – Hi-Flo ES was designed for maximum pack density, so stocking is easier than with any traditional pocket style filter.

Hi-Flo ES is a 5-Star ECI rated filter. Earning this top rating indicates that a filter is the most energy-efficient, and longest-lasting product in its class. Like all Camfil Farr filters, Hi-Flo ES is backed by the industry's most comprehensive performance guarantee.
