Hi sdemmet,
CertiPUR is a certification that only applies to polyfoam and memory foam so latex never has a CertiPUR certification.
Having said that … all the latex you are likely to encounter (either Dunlop or Talalay that is made with either natural or synthetic rubber or a blend of both) will have a reliable certification such as Oeko-Tex, Eco-Institut, and Greenguard Gold (see post #2 here) and C2C (see post #13 here) and based on actual testing I would consider any type or blend of latex to be a very “safe” material in terms of harmful substances and VOC’s.
Aireloom typically isn’t transparent about the materials in their mattresses and in general are one of the manufacturers that I would tend to avoid (see this article)
There is more information about the 3 most important parts of the “value” of a mattress purchase in post #13 here which can help you make more meaningful quality/value comparisons between mattresses in terms of suitability (how well you will sleep), durability (how long you will sleep well), and the overall value of a mattress compared to your other finalists based on suitability, durability, and all the other parts of your personal value equation that are most important to you (including the price of course and the options you have available after a purchase if your choice doesn’t turn out as well as you hoped for).
While nobody can speak to how any specific mattress will “feel” for someone else or whether it will be a good “match” in terms of comfort, firmness, and PPP (Posture and alignment, Pressure relief, and your own Personal preferences) because this is too subjective and relative to different body types, sleeping positions, and individual preferences, sensitivities, and circumstances and you are the only one that can feel what you feel on a mattress … outside of PPP (which is the most important part of “value”), the next most important part of the value of a mattress purchase is durability which is all about how long you will sleep well on a mattress. This is the part of your research that you can’t see or “feel” and assessing the durability and useful life of a mattress depends on knowing the specifics of its construction and the type and quality of the materials inside it regardless of the name of the manufacturer on the label (or how a mattress feels in a showroom or when it is relatively new) so I would always make sure that you find out information listed here so you can compare the materials and components to the quality/durability guidelines here to make sure there are no lower quality materials or weak links in a mattress that would be a cause for concern relative to the durability and useful life of a mattress before making any purchase.
If for any reason a retailer or manufacturer is either unwilling or unable to provide you with all the information you need about the materials and components inside a mattress you are considering to make an informed choice and to make more meaningful comparisons with other mattresses (which is most likely with Aireloom) … I would avoid the mattress completely because the risk of purchasing it would be much too high.
I would also make sure that you’ve read the mattress shopping tutorial here which includes all the basic information, steps, and guidelines you will need to make the best possible choice … and perhaps more importantly know how and why to avoid the worst ones.
If you let me know your city or zip code I’d also be happy to let you know about the better options or possibilities I’m aware of in your area.
