PET Carpet Vs Nylon Carpet is a common query for homeowners deciding on durable, stain-resistant, and eco-friendly flooring. This article compares performance, cost, sustainability, maintenance, and installation factors to help decide between PET (recycled polyester) and nylon carpet for American homes, apartments, and commercial spaces.
| Factor | PET Carpet | Nylon Carpet |
|---|---|---|
| Origin | Made From Recycled PET Bottles | Synthetic Polyamide Polymer |
| Durability | Moderate; Best For Low-To-Moderate Traffic | High; Excellent For High-Traffic Areas |
| Stain Resistance | Good (Hydrophobic); Prone To Oil-Based Stains | Very Good; Often Treated For Enhanced Resistance |
| Cost | Lower To Mid-Range | Mid-To-High Range |
| Sustainability | High (Recycled Content) | Lower (Petrochemical-Based) |
| Colorfastness | Excellent; Holds Vivid Dyes | Very Good; Slight Fading Possible Over Time |
What Is PET Carpet?
PET carpet, also called recycled polyester carpet, is manufactured from post-consumer PET bottles and recycled polyester fibers. The fiber is processed into staple or filament yarns and then tufted or woven into carpet. PET appeals to buyers seeking sustainable materials with good color retention and affordable pricing.

What Is Nylon Carpet?
Nylon carpet refers to fibers made from polyamide polymers; it is the industry standard for resilience and longevity. Nylon is engineered for high-traffic performance and is frequently used in homes, offices, and commercial spaces where durability and fiber recovery matter most.
Durability And Resilience
Durability depends on fiber structure, twist, pile density, and backing. Nylon consistently outperforms PET in resilience and fiber recovery, resisting matting and crushing better in hallways, stairs, and commercial settings.
PET can perform well in low-to-moderate traffic rooms such as bedrooms, guest rooms, and low-use living spaces, but it may show wear sooner under heavy, continuous use.
Stain Resistance And Cleaning
PET is inherently hydrophobic and repels water-based stains effectively; it resists dye migration and holds bright colors. However, PET can attract and retain oil-based stains—cooking oil, grease, and some cosmetics—making cleanup more challenging.
Nylon readily accepts stain treatments at the fiber level and many nylon carpets include stain-resistant finishes such as stain-blocking chemistries and soil-release technologies. With proper treatment, nylon handles both water- and oil-based stains better than PET.
Appearance And Color Options
Both PET and nylon offer a wide range of colors and textures. PET excels at holding vivid, saturated colors due to its affinity for disperse dyes, so PET produces vibrant, fade-resistant carpets ideal for modern designs.

Nylon provides a broad palette and often supports more textured, sculpted, and high-performance constructions, making it a go-to choice for varied styles and commercial-grade appearances.
Comfort And Feel
Hand and softness vary by fiber denier, twist, and pile height. Nylon fibers are typically softer and springier, providing a cushioned, resilient feel underfoot when paired with quality pads. PET can match softness when manufactured as fine denier fibers, but may feel less springy over time in heavy-use areas.
Cost Comparison
PET carpet generally sits in the lower-to-mid price range because of recycled feedstocks and cost-effective manufacturing. Nylon tends to be more expensive due to higher performance specs, advanced treatments, and longer expected service life.
When evaluating cost, include expected lifespan, maintenance costs, and replacement frequency. Nylon may cost more upfront but deliver a lower cost-per-year in active households.
Environmental Impact And Sustainability
PET carpet has strong sustainability credentials since it uses post-consumer recycled plastic bottles. Choosing PET reduces landfill waste and lowers demand for virgin petroleum-derived fibers.
Nylon is petrochemical-based and consumes more energy during production, but recycling programs for nylon exist and some suppliers produce partially recycled nylon or adopt lower-impact manufacturing practices. Overall, PET is usually the greener choice for environmentally conscious buyers.
Allergy, Indoor Air Quality, And VOCs
Both PET and nylon carpets can meet indoor air quality standards when produced with low-VOC adhesives, backings, and padding. Look for carpets with Green Label Plus or similar certifications to minimize off-gassing and ensure better indoor air quality.
Regular vacuuming and proper ventilation reduce allergens regardless of fiber. PET’s recycled origin does not inherently increase allergen risk.

Performance In Different Rooms
Best Uses For PET Carpet: Bedrooms, low-traffic living rooms, playrooms, and rental units where affordability and color retention matter. PET performs well in spaces where oil exposure is minimal.
Best Uses For Nylon Carpet: Hallways, stairs, family rooms, offices, and commercial settings that require high durability, resilience, and easier oil-stain cleaning.
Maintenance And Care
Both fibers benefit from scheduled vacuuming with a HEPA or high-filtration vacuum and immediate spill response. For PET, use cleaning agents specifically formulated to tackle oil-based stains and follow manufacturer recommendations to avoid permanent marks.
Nylon accepts a wider range of cleaning chemistries and often shows better results with professional extraction cleaning. Periodic professional cleaning every 12–24 months extends life and appearance.
Installation And Backing Considerations
Carpet performance also depends on installation quality and pad selection. Choose a dense, high-quality pad to enhance comfort and resilience for either PET or nylon installations.
For stairs and high-traffic zones, tighter installation tolerances and secure seams reduce premature wear. Qualified installers ensure warranty compliance and optimal performance.
Warranty And Lifespan
Nylon carpets commonly carry longer warranties reflecting their higher resilience and commercial-grade performance. Warranties may cover wear, staining, colorfastness, and defects, but details vary with fiber treatments and backing systems.
PET warranties are improving as manufacturers refine processes, yet typical PET products may have shorter wear warranties than premium nylon offerings.
Cost-Per-Year Example
| Scenario | PET Carpet | Nylon Carpet |
|---|---|---|
| Upfront Cost (Per 200 Sq Ft) | $1,200–$1,800 | $1,800–$3,200 |
| Estimated Lifespan | 7–12 Years | 10–20 Years |
| Estimated Cost Per Year | $100–$257 | $90–$320 |
Costs vary widely by brand, style, installation complexity, and local labor rates. This table gives a general framework for budget planning.
Common Misconceptions
Myth: “PET Is Low-Quality.” Reality: Modern PET fibers can be engineered for softness and colorfastness, though not all PET products are equal.
Myth: “Nylon Stains Easily.” Reality: Untreated nylon can stain, but most nylon carpets are treated for stain resistance and are easier to clean than PET for oily spills.
How To Choose Between PET And Nylon
Assess household traffic patterns, pets, children, budget, and environmental priorities. Choose PET if sustainability and vibrant color at a lower price point matter most.
Choose nylon if high traffic, long lifespan, and superior resilience justify the higher initial investment.
Questions To Ask Retailers
- What Is The Fiber Content And Recycled Content Percentage? Verify PET’s post-consumer resin percentage or nylon’s recycled content.
- What Stain Treatments Are Applied? Ask about fiber-level treatments and warranty coverage for common spills.
- What Is The Recommended Padding And Installation Method? Proper pad selection can improve longevity and feel.
- What Certifications Does The Product Hold? Look For CRI Green Label Plus, NSF-140, or other environmental/health certifications.
Case Studies And Use Examples
Example 1: A young couple with a moderate budget chose PET carpet for bedroom and guest areas to maximize color and sustainability while installing nylon in the living room and stairs for durability. This hybrid approach balanced cost and performance.
Example 2: A daycare center selected commercial-grade nylon with specialized stain treatments and low-VOC backing to handle heavy traffic, spills, and frequent cleaning, prioritizing longevity and ease of maintenance.
