Lindhaus Type PH4 / L4 Vacuum Bags (10 Pack) + 2 Micro Filters

These are the genuine Lindhaus PH4 / L4 bags, part 030610019 — the bag for Lindhaus’s HEPA-capable commercial uprights. Ten bags and two micro-filters in the box, which Lindhaus prints on the carton as an estimated one-year supply. Which machines take this bag RX eco FORCE 380E, plus the 450E and 500E HEALTHCARE Pro eco FORCE, 12 inch and 14 inch CH Pro eco FORCE Do not confuse this with the A4 Lindhaus makes two paper bags of almost exactly the same size for its uprights, and they do not interchange. This is the PH4/L4, sold in tens. The other is the A4, sold in eights, and it fits the Activa, Diamante and Dynamic. The quickest check is the count in the last box you bought — ten means PH4, eight means A4. Not sure? Call 888-565-6163 with your model number and we will tell you straight away. Specifications Lindhaus part number 030610019 Type PH4, also stamped L4 In the box 10 multi-media paper bags, 2 hospital-grade micro-filters Capacity About 4 liters (4 quarts) Material Multi-layer high filtration paper Filtration Certified 98.28% net efficiency at 0.3 micron Genuine Yes — Lindhaus original, not an aftermarket copy The two filters are worth more than people realize Lindhaus prints a $9.95 retail value on the carton for the two micro-filters alone, which is a third of what the whole box costs. They are not a giveaway — they are the exhaust stage that keeps fine dust out of the room, and they are the part most owners never change. Fit a fresh one about halfway through the ten bags and again when you open the next box. On a machine used in a clinic, a care home or a school, that is the difference between filtration that works and filtration that is technically installed. Why not a generic bag Copies of this bag are sold for around half the money and they will physically fit. What they generally do not match is the paper. On a Lindhaus the bag is the first filtration stage, rated on its own at 98.28% down to 0.3 micron. A thinner copy passes more of that fine dust straight through to the motor filter, which clogs early and quietly costs you suction. On a commercial machine built to run for fifteen years, the saving is not where it looks. Is PH4 the same as L4? Yes — same bag, two names, both printed on the same Lindhaus carton. You may also see it cross-referenced as R4, 141299001 or 141296200 by other sellers. The Lindhaus part number is 030610019. How do I know I have the right one? Go by your machine, not by the look of the bag. RX eco FORCE, HEALTHCARE Pro and CH Pro take this one. Activa, Diamante and Dynamic take the A4. If you are unsure, call 888-565-6163 with the model name off the machine. Are the included filters HEPA? No. They are the electrostatic micro-filters these machines use as standard, which Lindhaus calls hospital grade. Certified HEPA is a separate optional filter for the machine itself — call us if you need one, particularly if a contract specifies it. How often should I change the bag? Lindhaus calls a box of ten about a year of normal use. In daily commercial work it will be a good deal less — change it when the suction starts to drop rather than waiting for it to look full. What about my Valzer, LB3 or LB4? All different. The Valzer and LB3 take the LB3 bag pack; the LB4 backpack takes its own microfiber bag. The HF6 canister takes the 14-liter HF6 bag.
