What are H 54, H 104 and H 300 water filters?
What specifications and features does the H 54 filter offer?
The H 54 filter offers a 3-stage filtration system with 5-micron sediment, granular activated carbon and a 0.01-micron ultrafiltration membrane. This model delivers up to 1.5 gallons per minute at 80 psi, removing 99.5% of particles ≥0.1 micron, including chlorine, cysts and some bacteria. Its stainless steel housing resists corrosion and can be footprint-mounted in a closet or under a countertop. The cartridge replacement interval is every 12 months or 3,000 gallons, and each sediment cartridge is NSF International certified to reduce sand, rust and scale.
Integration with existing plumbing uses a ¾-inch inlet, and the filter includes pressure gauges to monitor differential pressure before and after the membrane. Installation requires basic piping tools and a standard flange, making it suitable for kitchen sink retrofits or small office water treatment. This balanced approach to sediment and microbial reduction makes H 54 an economical choice for households prioritizing reliable chlorine taste removal and moderate particulate control.
What specifications and features does the H 104 filter provide?
The H 104 filter provides a 4-stage process featuring a 1-micron pleated sediment cartridge, catalytic carbon block, 0.005-micron nanofiltration membrane and a post-filter polishing stage. It supports up to 2.0 gallons per minute at 100 psi, reducing up to 98% of lead, giardia, cryptosporidium and organic compounds that cause odor and taste issues. The catalytic carbon block also breaks down chloramines, while the nanofiltration module captures calcium and magnesium to soften water slightly.
Maintenance involves replacing the pleated cartridge every 6 months or 2,500 gallons and the membrane every 24 months. Its rugged cast-iron mounting bracket and quick-change clamps enable tool-free cartridge swaps, minimizing downtime for businesses. By combining sediment, catalytic carbon and nanofiltration, the H 104 excels in removing fine particulates and heavy metals while preserving beneficial minerals.
What specifications and features does the H 300 filter deliver?
The H 300 filter delivers an advanced reverse-osmosis system with a five-stage sequence: 5-micron sediment, carbon block, reverse-osmosis membrane (0.0001-micron), deionization resin and UV disinfection. This setup removes up to 99.9% of dissolved solids, bacteria, viruses, lead, arsenic and fluoride. Despite the tighter membrane, it achieves 0.5–1.0 gallon per minute flow using an integrated booster pump that maintains 120 psi across the membrane.
Cartridge and membrane replacements occur every 12 months for pre-filters and every 36 months for the RO membrane. The deionization resin requires annual service, and the UV lamp requires replacement after 9,000 hours. This model’s alloy pump and stainless steel fittings resist corrosion in low-mineral water and make H 300 ideal for point-of-use systems where total dissolved solids must be minimized, such as laboratory sinks or ice machines.
How do H 54, H 104 and H 300 models compare in performance and cost?
A side-by-side comparison table highlights flow rate, pore size, maintenance interval and list price across the three filters. This makes it easier to match system capabilities with household or business water quality and budget constraints. These performance metrics also reflect the varying levels of osmosis, membrane filtration and post-treatment polishing in each model.

As shown, the H 104 filter maximizes flow and fine-particle removal with a mid-range investment, while the H 300 excels at total dissolved solids reduction but at a lower flow rate and higher list price. The H 54 balances moderate flow and ultrafiltration for chlorine and sediment control at an entry-level cost. Factor in filter fee and service ease when deciding which model aligns with your kitchen, bathroom or industrial application.
What are customers saying about H 54, H 104 and H 300 filters?
Customer feedback often highlights ease of cartridge replacement, taste improvement and consistent pressure. Positive reviews note a 45% reduction in chlorine taste (tested by independent lab in 2023) and near-elimination of sediment in homes with galvanized piping. Negative comments occasionally mention slower fill rates on H 300 systems without booster pumps.
-
H 54 users praise the balanced sediment and carbon stages for cleaner drinking water without over-drying.
-
H 104 owners cite strong performance on lead removal and catalytic breakdown of chloramines in municipal supplies.
-
H 300 adopters appreciate near-zero TDS water for appliances, though installation demands more space and a drain line.
-
All three filters receive high marks (4.6/5 average) for assembly ease, thanks to quick-change clamp systems.
-
Annual maintenance and replacement costs vary from $80 to $150 per year, depending on membrane choice.
Which water filter model—H 54, H 104 or H 300—should you choose for your home?
Choosing the right model depends on your primary water quality goals: sediment/cl‐chlorine taste removal (H 54), heavy‐metal and chloramine reduction (H 104), or ultra-pure low-TDS water (H 300). For a standard kitchen tap aiming to improve taste and reduce particulates, H 54 offers the best value. If lead or cryptosporidium are concerns in city water, H 104 strikes an optimal balance of flow and contaminant removal. And for laboratory-grade purity or appliance protection, the H 300 reverse-osmosis system is unmatched despite its lower flow rate.

How often should I replace the cartridge in an H 104 filter?
The pleated sediment and carbon cartridge in H 104 should be replaced every six months or 2,500 gallons to maintain optimal flow and removal rates.
Can the H 300 filter remove lead and giardia?
Yes; H 300’s reverse-osmosis membrane and UV stage remove up to 99.9% of lead, giardia and other pathogens.
Do these filters require a booster pump for adequate flow?
Only the H 300 model uses an integrated booster pump for its tight RO membrane; H 54 and H 104 operate at standard household pressure.
Are H 54 and H 104 compatible with countertop installations?
Yes; both models feature compact housings and standard ¾-inch inlet fittings that work with countertop faucet adapters.
Which filter offers the lowest total dissolved solids?
The H 300 reverse-osmosis system delivers the lowest TDS down to 10 ppm, ideal for special applications.
Conclusion
Selecting between H 54, H 104 and H 300 boils down to your filtration priorities: sediment and taste, heavy-metal capture or ultra-pure water. Each model’s specifications—flow rate, membrane pore size and maintenance schedule—align with distinct applications in the kitchen, whole-house or point-of-use systems. Reviewing contaminant removal data and customer feedback helps clarify which filter meets your quality goals and budget.
