The 30-Second Verdict
Culligan is the full-service local-dealer model — they design, install, service, and maintain your system with a local franchise. Expect higher upfront and ongoing service costs, but you also get someone to call when the system fails. Aquasana is the DIY/installer-of-your-choice model — you buy direct, hire a plumber to install, and own the system outright. For Florida’s hard, sulfur-prone, and well-water-fed homes, Culligan’s tailored multi-stage approach handles edge cases better. For city water in a typical Florida suburban home where you mainly want better taste and chlorine removal, Aquasana wins on price and quality.
Head-to-Head Breakdown
Culligan
Pros
- Free water test + system sized to your exact contaminants
- Local dealer handles install, service, and salt delivery
- Strong in well water, iron, sulfur (rotten-egg smell), and arsenic removal
- Service contract option keeps the system running 15–20 years
- Rent-to-own option available (no upfront cost)
Cons
- Premium pricing — typical whole-house + softener runs $4,500–$8,500 installed
- Salt delivery contracts add $30–$50/month ongoing
- Brand-locked replacement parts (proprietary cartridges)
- Dealer quality varies — some Florida franchises are aggressive on rent-to-own contracts
Aquasana
Pros
- Direct purchase — $1,200–$2,800 for whole-house carbon + salt-free softener
- Use any local Florida plumber for install ($400–$1,000)
- No ongoing service contract or salt delivery
- Salt-free softener uses TAC (template-assisted crystallization) — no waste water, no sodium added
- 1M-gallon Rhino whole-house filter lasts 5–10 years
Cons
- DIY-friendly but installation still requires a licensed plumber for whole-house
- Salt-free softening doesn’t reduce hardness numbers — just changes scale form (some homeowners want true softening)
- Less effective on very hard well water or high iron/sulfur (Culligan is better for that)
- Replacement filters bought online — no local service relationship

Frequently Asked Questions
Should I get true softening or salt-free for Florida water?
If your home is on city water and hardness is 5–15 grains/gallon (typical Florida municipal), salt-free TAC (Aquasana, SpringWell, etc.) works well — no salt, no waste water, no sodium added to your drinking water. If you’re on well water or hardness exceeds 15 gpg, traditional ion-exchange softening (Culligan, Kinetico) is more effective — you’ll see real reduction in scale on fixtures and longer water-heater life.
Will Aquasana handle Florida well water?
Aquasana’s default Rhino whole-house filter handles chlorine, chloramine, and some VOCs but NOT iron, sulfur (rotten-egg smell), or high TDS. For Florida well water, you’d need to stack Aquasana’s filter behind a separate iron/sulfur pre-filter — doable, but at that point Culligan’s integrated multi-stage system is often easier and only slightly more expensive.
Is the Culligan rent-to-own contract a good deal?
Usually no. Rent-to-own contracts run $50–$100/month for 5–10 years and end up costing 2–3x the system’s purchase price. If you can finance the system directly or pay cash, you’ll save thousands. The rent-to-own works only if you genuinely can’t qualify for any other financing.
Which is more common in Florida?
Culligan has 30+ local franchise locations across Florida and is the dominant brand in well-water-heavy regions (rural Pasco, Polk, Marion counties). Aquasana has no physical Florida presence — you buy direct online — but is widely used by homeowners doing DIY whole-house installs.
