What Filterit Oy does

Filterit Oy is a Helsinki-based, privately held Finnish company specializing in industrial water treatment and filtration equipment, operating since 2005 with a lean team of 6 employees. The company distributes and supplies a broad portfolio spanning mechanical filtration (self-cleaning filters, bag filters, cartridge filters, centrifugal separators, drum and disc filters), ultrafiltration (C-MEM hollow fiber technology, C-TECH activated sludge treatment), reverse osmosis (APRO series ranging from 60 l/h household units to 48,000 l/h industrial modular systems), UV disinfection (low-pressure and medium-pressure systems for clean water, wastewater, and swimming pools), chemical-free water treatment (Scalebuster cavitation technology), ozonation, and plasma-based disinfection (CUBUSAN indoor air device and C-ION advanced oxidation process). Proprietary technologies include Fraunhofer-certified CUBUSAN cold plasma air disinfection, C-ION AOP for pharmaceutical residue removal, self-sterilizing FilterAFM glass media, and multi-function FilterCR filters with 20-year media lifespan.

The company operates on a direct sales-led go-to-market model through its own sales team in Helsinki, selling primarily to industrial customers (food and beverage, chemical, pharmaceutical, mining, paper/pulp, steel, power plants), municipal water utilities, HVAC service providers, and residential/commercial properties across Finland. Revenue is generated through hardware sales of treatment equipment and a recurring spare parts business supplying UV lamps, quartz tubes, and sensors compatible with both its own and other manufacturers' UV systems. Pricing is not publicly disclosed and quotes are provided on a project basis. The company maintains an English-language website, indicating some international outreach, and publishes technical blog content targeting emerging niches such as data center cooling water and ice arena water treatment.

Filterit is independently owned with no disclosed external investors, no funding rounds, and no M&A activity. Management is led by Tomi Virtanen as Managing Director, supported by a product manager and a sales force covering the Finnish market. The company serves as a value-added reseller and engineering consultant for complex water treatment applications, with no manufacturing disclosed and no AI/ML capabilities in its product stack.

Products and services

• APRO Reverse Osmosis Systems Modular APRO reverse osmosis units for industrial and household water purification. Achieves conductivity below 15 µS/cm (Class III nearly salt-free water). Models include APRO DP60 (60 l/h, dual-pump), APRO 3000/4000/6000 (modular up to 48,000 l/h), APRO-CT (brackish/Baltic water), APRO-HC (high salt, large flow), APRO-HS (seawater, TDS max 10,000), APRO-HP (99.7% salt rejection), and APRO-1000-WH (whole-house with 80L tank and integrated post-mineralization). Energy-efficient Grundfos pumps reduce electricity consumption by up to 50%.
• CUBUSAN Indoor Air Disinfection Device Continuous indoor air and surface disinfection device using Sterex cold plasma technology producing hydroxyl radicals from room air moisture. Destroys 99.99% of bacteria, viruses, and fungal spores including SARS-CoV-2 and its mutations. Covers up to 120 m³ (48 m² at 2.5 m ceiling height). Noise level 32 dB, power consumption under 25 W, maintenance-free with 25,000-hour plasma unit and fan life. Tested and certified by Fraunhofer Institute.
• C-ION Advanced Oxidation Process (AOP) Cold plasma (NTP) based advanced oxidation process for wastewater treatment. Generates reactive oxygen radicals that oxidize organic and inorganic impurities. Does not require chemicals or combination with other disinfection techniques. Suitable for very high solids loads and poorly oxidizable compounds such as pharmaceutical residues in wastewater.
• C-MEM Ultrafiltration Systems Hollow fiber-based ultrafiltration membrane technology with pore size of 20.1 nm. Suitable for drinking water, process water, river and lake water, and wastewater treatment. Hydrophilic hollow fibers maximize surface area, wound around a collecting tube and protected by a plastic shell. C-MEM Zero variant enables production of drinking water from lake/river or poor-quality well water without electricity or pumps.
• C-TECH Activated Sludge Treatment System Continuous activated sludge treatment technology for more efficient wastewater treatment with reduced footprint compared to traditional SBR batch processes.
• FilterAFM Sand Filter Media and Hypersand Filtration Activated broken glass media for hypersand filtration achieving 1 µm filtration accuracy versus 25-50 µm for conventional sand filters. Self-sterilizing due to catalytic surface producing free radicals. Zeta potential attracts heavy metals and organic molecules. 1 kg of AFM provides 50 m² of filtering surface vs 3 m² for conventional sand. Requires over 50% less water for backwashing.
• FilterCR Multi-Function Filters Single filter unit solving multiple water problems simultaneously: water softening (limescale removal), iron removal, manganese removal, pH balancing, ammonium removal, and organic matter removal. FilterCR filter media has a lifespan of up to 20 years. Built-in chlorine generator for self-disinfection during backwashing.
• Scalebuster Chemical-Free Water Treatment Device Cavitation and static electricity-based device protecting pipes and water systems from corrosion and scale buildup without chemicals or power supply. Sizes DN15-DN600, PN10/16/40 pressure ratings, flow rates 0.05-2,840 m³/h. Certified for drinking water (ACS, TUV GS, WRAS approvals).
• UV Disinfection Systems UV disinfection devices for clean water applications, chemical-free wastewater disinfection (destroying up to 99.99% of harmful microorganisms), medium-pressure UV systems for swimming pool chloramine removal and industrial wastewater chemical compound removal, and TOC reduction via 185 nm hydroxyl radical oxidation.
• Ozonation Systems Ozonation systems using ozone as a powerful oxidizer for effective disinfection without added chemicals, deployed where other disinfection methods are insufficient, with low operating costs.
• Water Softeners (Ion Exchange) Ion exchange-based water softeners that remove calcium and magnesium ions using cation resin, serving industrial, water plant, property, and household applications.
• FilterAir Iron and Manganese Removal Filter Oxidizing mass filter designed for iron and manganese removal from water.
• FilterCarb Activated Carbon Filter Active carbon filter that removes odor, taste, color, organic compounds, chlorine, and radon from water through activated carbon adsorption.
• FilterpH Neutralization/Alkalization Filter Neutralization/alkalization filter using limestone gravel for pH adjustment of acidic water in properties and households.
• Mechanical Filtration Equipment Portfolio Range of mechanical filtration equipment including automatic self-cleaning filters (backflushing, co-current flushing, mechanical cleaning), arc screens for high solid loads, basket and double basket filters for liquids and gases, centrifugal separators using centrifugal force, cartridge filters (500 µm to 0.02 µm), bag filters (deep-filtering, surface-filtering, oil-absorbing), and drum and disc filters for large flow rates in non-pressurized applications.
• UV Lamps and Spare Parts UV lamps, quartz tubes, sensors, filter bags, and filter cartridges supplied as replacement parts for the company's own equipment as well as other manufacturers' UV disinfection devices, including ULTRAAQUA, AQUAFIDES, WEDECO, TROJAN, PROMINENT, BEST UV, BERSON, and SITA.
