Polyester Carpet Pros and Cons

If you’ve ever poured ketchup on a hamburger or drove a car, you might have started the manufacturing process of someone’s polyester (PET) carpet. This unique carpet is made from recycled tires and bottle caps. Unfortunately, the good intentions of this carpet often prove to be much better than the carpet itself. Polyester carpet has flaws that make its use limited, but if you utilized correctly, you may be a proud owner of 100% recycled carpet.

Polyester CarpetCaptain’s warning! There is a new type of polyester on the market, but this page is referring to traditional polyester. How do you know the difference? If you’re shopping and are told you’re looking at a polyester carpet, it’s the “old” or traditional polyester. The new polyester, technically PTT polyester, going by the name Smartstrand and is rarely called polyester. You can read more about Smartstrand carpet here.

Only 100% recycled carpet

This was touched on earlier, but it’s worth repeating since it’s a unique advantage and one of the few advantages polyester has over other carpet materials. Synthetic polyesters found in bottle caps and tires are non-biodegradable. Therefore, reusing these materials is appreciated by Mother Nature who is being taken over by ever-expanding landfills.  In addition, it’s one less carpet that has to be pumped out in a factory.

Update: A member of CARE contacted me and had issue with polyester being ranked highly as a “green” carpet. His point was that, yes, PET polyester may be made out of recycled materials at times, but it cannot be recycled like nylon or olefin can. Makes sense, so we downgraded polyester from an ‘A’ grade to a ‘C’ in the green category.

Great stain resistance (except for oils)

Polyester fibers are naturally great at stain resistance. Spill your drink? No problem. Blot it up and you probably won’t know it happened. Brands like DreamWeaver Carpet heavily advertise this.

The only downfall in the stain resistance department is polyester attracts oils. We find oils everywhere: our skin, the bottom of our shoes from asphalt, tracked in from the kitchen or garage. You probably won’t notice oils on the carpet, except that they attract dirt. Often times, a dirty looking carpet is an oily one.

Brilliant colors

Like bright colors? Polyester may be your choice. Polyester is easier to dye in bold colors than some other carpet fibers. With this in mind, 98% of the time you can find the color you want in any carpet fiber with today’s technology.

Crushes easily

This one heading sums up what I don’t like about polyester. It’s a soft fiber that doesn’t last well under foot traffic. It eventually mats down or crushes, and this makes carpet look more worn out than anything. If you have a decent amount of traffic (any main living area or area with kids), don’t buy polyester and expect it to last much more than 5 years.


One nice touch to polyester is its cheap. You can sometimes find polyester under $1 a square foot (although sometimes it can also be much more than this). This can make it a great carpet if you just want something now and are on a tight budget, or if you know your carpets going to get destroyed and want to save on cost

Nylon vs polyester

I rarely talk to someone about polyester carpet without nylon coming up. The funny thing is these two carpets are completely different. Nylon is much more durable, but it also costs more. If you’re interested, I have a full page on nylon vs polyester carpet.

Captain’s parting words!

If it weren’t for its lack of durability in main living areas, I love polyester. It’s great at resisting stains, it comes in beautiful colors, it’s soft, and the most unique of them all, it is 100% recycled.

Areas like guest rooms, family rooms with little traffic, or homes with only an adult or two (no kids) can be great for polyester. If you want polyester in a higher-traffic room, you really need to pay attention to everything that impacts carpet durability. and even then it may not be the best choice.

How well do you think perpetual 2 by Shaw will hold up?

Lara Keck

We are considering a PET Polyester carpet by Shaw called Momentum I to recarpet 4 bedrooms (Master, Guest, 2 teen daughters). Stats are as follows: Pile Density is 3120, Pile Height is .36, Face Weight is 31.20, Tuft Twist is 6.05, Anti Stain is R2X. We’d like to see maybe 7 years out of this carpet. Is that a reasonable estimate? How do you think it will hold up? Thank You.

I’m considering 100% SmartStrand Triexta, Sorona Silk, density 2461, lower tha. 2900 recommended on this site, twist is 6., pile wgt 45, no pets, not heavy traffic, I’m concerned about the lower density, looking for your opinion on this carpet, this is more confusing than I ever thought!
Thank you!

What do you think of a poly carpet with 79 face weight, 4.25 twist? Will it still crush easily? I am considering it vs 60 face weight nylon. Thanks

Since you’re carpeting major traffic areas, I’d go with the nylon. A high face weight polyester may not be bad, but I take fiber type of face weight. I’d expect you to get a few more years out of the nylon.

How would you rank the quality of a carpet with 60% smart strand 40% pet polyester?

Would love your thoughts, please comment.x
