Why the Frigidaire ULTRAWF & PAULTRA Combo Pack Is the Complete Filtration Solution for Compatible Frigidaire Refrigerators

Your Frigidaire refrigerator relies on two separate filtration systems to deliver clean water and a fresh interior environment every day. The ULTRAWF PureSource Ultra water filter handles what goes into your glass. The PAULTRA Pure Air Ultra air filter handles what circulates inside the cabinet. When both are due for replacement at the same time, the Frigidaire ULTRAWF and PAULTRA combo pack covers both in a single order at the best price, keeping your refrigerator performing at full capacity on a shared six month replacement schedule. This guide explains exactly what each filter does, how to confirm this is the right combo for your specific Frigidaire model, and when to order a fresh replacement.

What the Frigidaire ULTRAWF & PAULTRA Combo Pack Actually Covers

The ULTRAWF and PAULTRA combo pack addresses two completely separate filtration functions inside your Frigidaire refrigerator that both operate on the same six month replacement cycle.

The ULTRAWF PureSource Ultra water filter is the water-side component. It sits inside the fresh food compartment filter housing and processes every drop of water that passes through the dispenser and ice maker before it reaches your glass or ice tray. Every contaminant the ULTRAWF is rated to reduce , chlorine, lead, cysts, sediment, and VOCs , is captured before the water leaves the housing rather than after.

The PAULTRA Pure Air Ultra air filter is the air-side component. It sits inside the fresh food compartment and works continuously as cabinet air circulates across its activated carbon surface. Its job is to capture odor-causing compounds and ethylene gas before they accumulate to levels that affect food freshness and cabinet odor. It operates silently and continuously without any moving parts or power consumption of its own , the natural air circulation inside the refrigerator cabinet drives the filtration process.

Neither component substitutes for the other and neither filter affects the other's function. Replacing only the water filter leaves the air quality side unaddressed. Replacing only the air filter leaves dispensed water filtration unaddressed. The ULTRAWF and PAULTRA combo pack is the most practical and cost-effective way to address both at the same time for compatible Frigidaire refrigerator models.

Why the Frigidaire ULTRAWF PureSource Ultra Water Filter Matters

The Frigidaire ULTRAWF PureSource Ultra is an NSF 42 and 53 certified replacement water filter designed for compatible Frigidaire French door and side-by-side refrigerator models. Understanding what the certification levels actually mean helps put the replacement schedule in proper context.

What NSF 42 and 53 certified water filtration means:

NSF 42 certification means the ULTRAWF has been independently tested and verified by a third-party laboratory to reduce chlorine taste and odor to below the NSF standard threshold under controlled conditions. Chlorine is added to municipal water supplies as a disinfectant. While necessary for public health, chlorine and its byproducts are the primary reason unfiltered tap water and refrigerator water from an exhausted filter taste noticeably flat or slightly chemical. A functioning ULTRAWF strips chlorine compounds from the water stream before they reach the dispenser, which is why water from a recently replaced filter tastes measurably cleaner than water from a filter running past its rated service life.

NSF 53 certification means the ULTRAWF has been independently verified to reduce health-related contaminants including lead and cysts to below the NSF 53 standard threshold. Lead contamination is a particular concern in older homes where aging service pipes introduce lead into the household water supply regardless of municipal treatment quality. NSF 53 certified lead reduction on the ULTRAWF means this claim has been tested and verified through independent laboratory methods rather than self-reported by the manufacturer.

The ULTRAWF PureSource Ultra is rated for 200 gallons or 6 months, whichever comes first. Alternative part numbers 242294402 and 241791601 refer to the same ULTRAWF filter format. If your existing water filter label shows either of those codes, the ULTRAWF is the confirmed replacement for your unit.

What the ULTRAWF reduces:

• Chlorine taste and odor through NSF 42 certified activated carbon block filtration
• Lead and heavy metals through NSF 53 certified contaminant reduction
• Cysts and sediment through mechanical and adsorptive filtration
• Volatile organic compounds through activated carbon adsorption
• Particulates affecting water clarity and ice appearance

Worth noting: whether these specific contaminants are present in your household water supply depends on local conditions. Requesting a current water quality report from your municipal provider is the most reliable way to assess which contaminants are relevant for your household.

Why the Frigidaire PAULTRA Pure Air Ultra Air Filter Matters

The Frigidaire PAULTRA Pure Air Ultra is a replacement air filter designed for compatible Frigidaire refrigerator models. It uses activated carbon filtration to reduce food odors and ethylene gas inside the fresh food compartment continuously throughout its six month service life.

How the PAULTRA Pure Air Ultra works and why it matters:

Activated carbon in the PAULTRA filter contains millions of microscopic pores that create an enormous effective surface area within a compact physical cartridge. As cabinet air circulates across this surface, odor-causing molecules and ethylene gas molecules bond to the carbon through a process called adsorption , physical bonding to the surface rather than absorption into the material itself.

Ethylene gas is the primary compound the PAULTRA targets and understanding what ethylene does inside a refrigerator cabinet explains why the air filter replacement schedule matters as much as the water filter schedule.

Ethylene is a colorless, odorless gas that fruits and vegetables release naturally as part of their ripening process. It functions as a biological signaling molecule , when a fruit reaches maturity it releases ethylene which signals nearby fruit to begin ripening as well. This mechanism works well in a natural outdoor environment where ethylene disperses freely. Inside a closed refrigerator cabinet the same gas accumulates to concentrations that dramatically accelerate ripening and spoilage across everything stored in the same space.

Apples, pears, avocados, bananas, stone fruits, and tomatoes are among the highest ethylene producers. Leafy greens, broccoli, carrots, cucumbers, and berries are among the most ethylene-sensitive , they deteriorate fastest when exposed to elevated ethylene levels. Storing high producers and high sensitives in the same refrigerator cabinet without effective air filtration creates exactly the conditions for accelerated spoilage regardless of how recently the produce was purchased.

A functioning PAULTRA Pure Air Ultra air filter keeps ethylene levels consistently low inside the cabinet, slowing the ripening feedback loop and meaningfully extending the usable life of stored produce. A household that replaces the PAULTRA on schedule typically notices that produce lasts noticeably longer between grocery trips compared to one running an exhausted or absent air filter.

The PAULTRA reaches adsorption capacity based on time and exposure rather than measurable throughput. Unlike the water filter which tracks gallon consumption, the air filter operates on a strictly time-based six month replacement schedule regardless of how much food is stored or how frequently the refrigerator door is opened.

Is the ULTRAWF & PAULTRA Combo the Right Combo Pack for Your Frigidaire Refrigerator?

Before buying the Frigidaire ULTRAWF and PAULTRA combo pack, confirm both part numbers against the existing installed filters in your refrigerator. This is more important for the air filter than the water filter since Frigidaire uses three distinct air filter formats across its refrigerator lineup.

Confirming the water filter: If your existing water filter label shows ULTRAWF, PureSource Ultra, 242294402, or 241791601, the ULTRAWF component of this combo is confirmed for your unit.

Confirming the air filter: If your existing air filter label shows PAULTRA or Pure Air Ultra, the PAULTRA component of this combo is confirmed. If it shows PAULTRA2 or Pure Air Ultra II, the EPTWFU01 and PAULTRA2 combo pack is the correct replacement for your unit. If it shows FRGPAAF2 or PureAir AF-2, the FPPWFU01 and FRGPAAF2 combo pack is the correct replacement. The PAULTRA, PAULTRA2, and FRGPAAF2 are three separate air filter formats with different housing designs that are not interchangeable.

Finding the part numbers: The part number is printed directly on each installed filter. The water filter housing is typically located in the upper right area of the fresh food compartment. The air filter housing is typically on the rear wall of the fresh food compartment. If either label is worn or unreadable, the refrigerator model number on the door frame sticker can be used to cross-reference the correct filter codes. Alternatively contact the Refrigerator Filters Shop support team at (646) 655-0227 or info@refrigeratorfilters.shop for part number confirmation assistance before ordering.

How the ULTRAWF & PAULTRA Combo Pack Compares to Other Frigidaire Combo Options

Understanding how the Frigidaire ULTRAWF and PAULTRA combo pack sits within the broader Frigidaire filter lineup helps buyers confirm they are ordering the right combination for their specific model.

The Frigidaire filter lineup includes three water filter options covered at Refrigerator Filters Shop , the ULTRAWF PureSource Ultra, the FPPWFU01 PurePour PWF-1, and the EPTWFU01 PureSource Ultra II , and three air filter options , the PAULTRA Pure Air Ultra, the PAULTRA2 Pure Air Ultra II, and the FRGPAAF2 PureAir AF-2. Each water filter covers a different range of Frigidaire refrigerator model generations and each air filter covers a different set of compatible housing designs.

The ULTRAWF and PAULTRA combo is specifically for Frigidaire refrigerator models that use both the ULTRAWF water filter and the PAULTRA air filter. It is not the correct combo for models that use the EPTWFU01 and PAULTRA2, or the FPPWFU01 and FRGPAAF2, or any other combination. The only reliable way to confirm the correct combo is to check the part numbers on both existing installed filters.

The Real Value of Buying the ULTRAWF & PAULTRA Combo Pack

Buying the best price ULTRAWF PAULTRA combo pack rather than ordering each filter separately delivers savings on every replacement cycle. Since both filters share a six month service life, most households replace them twice per year. The combo pack saving applies on every order, and over two to three years of consistent replacement cycles the accumulated saving over purchasing filters individually is meaningful.

Beyond direct filter cost savings, consider the broader value delivered. The ULTRAWF covers 200 gallons of filtered water per cartridge , the equivalent of approximately 400 standard plastic water bottles. At any bottled water price point, filtered refrigerator water represents a fraction of the per-gallon cost of buying bottled water while delivering NSF 42 and 53 certified contaminant reduction that most bottled water sources do not independently verify to the same standard. The PAULTRA air filter adds produce freshness value on top of that by reducing ethylene gas buildup that would otherwise accelerate spoilage between grocery trips.

Combined, the ULTRAWF and PAULTRA combo pack delivers clean, NSF 42 and 53 certified water filtration and activated carbon air purification for compatible Frigidaire refrigerators at the best price available at Refrigerator Filters Shop with free shipping across the USA.
