Filter sizing matters: too small and your water never clears, too big and you overspent. We match the filter to your pump and pool, quote upfront, and install ASAP.

Serving Arizona homeowners since 1998
Your filter must match your pump's flow rate and pool volume. Too small and the water never clears; too large and you overspent. Arizona's heavy dust loads push filters harder than average, so correct sizing from day one means cleaner water and fewer problems.
We size by your pump output, pool volume, and plumbing diameter. You see the full cost (filter + labor) before we order, and we plumb to your existing setup whenever possible.
Since 1998, we've installed cartridge, sand, and DE filters across Scottsdale, Cave Creek, Paradise Valley, and greater Phoenix. As a Pentair Certified Dealer, we back qualifying equipment with a 3-year warranty. We size by your system, not by what's easiest to stock. The right filter, properly matched and professionally installed.
MAKO Exclusive has been doing pool filter installation in Arizona since 1998. Filter installs are one of the more under-engineered pieces on a typical equipment pad. Most homeowners (and a fair number of pool companies) just swap whatever was there with the same size and type. That's fine if the original was sized correctly for the pool and pump. Often it wasn't. We size based on three things: pump turnover rate (gallons per minute at design point), pool volume, and the actual debris load you deal with. In Arizona, debris load is usually the surprise: monsoon dust and tannins from palo verde and mesquite trees push filters harder than the manufacturer's nominal rating.
Cartridge filters are the most common choice for residential Valley pools. They filter to about 10-15 microns (good), use no backwash water (great for water-conscious Arizona), and have no multiport valve to fail. The downside is cartridge replacement every 4-7 years and chemical cleaning every 4-8 weeks during peak season. We install Pentair Clean & Clear Plus, CCP series, and the larger Pentair Quad cartridges; Hayward SwimClear; Jandy CV/CL series; and Sta-Rite Posi-Clear.
Sand filters are simpler and cheaper but coarser (filters to ~20-30 microns). They require backwashing every 4-6 weeks (which uses water), and the media itself needs replacement every 5-7 years. Some Arizona pool owners prefer sand for ease of maintenance; if you don't mind the backwash water loss, sand filters are perfectly fine. We install Pentair Tagelus, Sand Dollar, and Hayward Pro-Series sand filters.
DE (diatomaceous earth) filters are the finest filtration option for residential pools (1-5 microns), but they're the highest-maintenance and we usually don't recommend them for first-time pool owners. They require backwashing plus DE powder recharge, and grid assemblies are delicate. They're great for show pools and pools where water clarity is paramount. We install Pentair Quad DE and FNS Plus if you want this level.
The biggest install mistake we see is undersized filters. A filter rated for 60 GPM paired with a pump capable of 80 GPM at low speed runs at maximum capacity continuously, which means the media wears out fast and pressure climbs quickly. The rule of thumb we use: filter capacity should be at least 1.5x the pump's design flow rate. For a typical Valley residential pool with a 1.5 HP variable-speed pump, that usually means a 200-420 square foot cartridge filter or equivalent. We do the math during the quote.
The other sizing factor is turnover time. A pool should turn over (filter through its entire volume) in 6-8 hours. For a 20,000-gallon pool, that's 40-55 GPM minimum flow. The filter has to handle that flow without exceeding 15-18 PSI clean. Most filter installs in the Valley get this right; some don't, and we'll flag undersizing during the quote and recommend a larger filter or higher-flow plumbing if appropriate.
A standard filter install includes: removal and disposal of the old filter, supply of the new filter and tank, installation of new unions, multiport valve (for sand/DE) or air-relief assembly (for cartridge), pressure gauge, plumbing connections to match existing layout, initial cartridge or sand/DE media load, leak test, pressure verification, and a walk-through on how to backwash or pull cartridges yourself if you want to do interim cleans between our visits.
Typical residential cartridge filter installs run $1,200-$2,200 all-in (filter and labor). Sand filter installs run $900-$1,500. DE filter installs run $1,500-$2,800. We typically schedule within a week of the quote. There's no diagnostic fee. For repair work on your existing filter, see pool filter repair. For full equipment-pad upgrades that pair filter installation with pump install or heater install, we offer bundled pricing.
